…-org#10214) The annotation conditions referenced the non-existent top-level .Values.existingSecret instead of .Values.auth.existingSecret, so the secret checksum annotation and the empty-secret gating never worked as intended when an existing secret wasn't supplied.
…rg#10251) CONCURRENTLY was being appended to the parenthesised option list alongside VERBOSE etc., which PostgreSQL rejects. It's not a parenthesizable option: it belongs standalone, between the object type keyword and the object name.
…min-org#9450) A role's membership tab only enabled the add/remove member controls for superusers and CREATEROLE holders, so a user who was themselves granted ADMIN OPTION on that role (and can therefore GRANT/REVOKE its membership at the SQL level) had no way to add other members, and hit a permission error server-side if they tried anyway. The role UI schema now also allows membership changes when the current user is a member of the role with admin=true. The backend mirrors this: permission.sql reports whether the connecting user holds ADMIN OPTION on the target role, and the update handler lets such a request through only when it's restricted to rolmembers changes, so this can't be used to escalate other role attributes.
…in-org#10309) validate_json_data() only checked that the Username key was present on a non-shared server, not that it held anything useful, so an empty or null value imported cleanly and left behind a server that libpq would silently authenticate as the OS account running pgAdmin rather than reject outright. Check the value, matching the truthiness check already used for shared servers and the "Username must be specified" rule enforced by the server dialog.
…mode (pgadmin-org#8991) execute_void() blindly reused whatever cursor was cached for the connection, which under "server cursor" mode is the named/server-side AsyncDictServerCursor left over from the last SELECT. A named cursor's execute() always wraps the statement as `DECLARE ... CURSOR FOR <query>`, which cannot express a transaction-control statement, so BEGIN/COMMIT/ROLLBACK silently failed (failing one step earlier still, on a `prepare` keyword the server-side cursor's execute() doesn't accept at all) and the exception was swallowed by the background query thread. The transaction was therefore never actually committed or rolled back, and the next poll() picked up the previous query's leftover column info, which is what made the result grid appear instead of the Messages tab. Run the statement through a throwaway plain cursor instead, leaving the cached server-side cursor untouched, and clear the stale column info so poll() correctly reports no result set.
…gadmin-org#10136, pgadmin-org#10137) create_shared_server() started dropping tags (hardcoded to None) and stripping passfile out of connection_params when materialising a per-user SharedServer copy, a regression from the 9.15 data-isolation hardening (9a76ed8, e4edcf2). Tags are now seeded from the owner's server as with the other copied fields, and passfile - the mechanism by which a shared server's owner lets every user authenticate automatically - is excluded from the SSL-path stripping that still rightly applies to sslcert/sslkey/sslrootcert/sslcrl/sslcrldir.

💡 Result:
The functions get_shared_server and create_shared_server are internal methods associated with the pgAdmin 4 project, specifically related to its shared server management and data isolation architecture [1][2]. In the pgAdmin 4 codebase (as observed in developments regarding server mode and security hardening), these functions are utilized to manage shared server properties and ensure proper access control [1][2]: - get_shared_server: This method is used within the pgAdmin server modules (e.g., pgadmin.browser.server_groups.servers) to retrieve the shared server instance associated with a specific user and server ID, facilitating the resolution of shared server overrides [1]. It is also employed to simplify operations like clearing saved passwords or SSH tunnel passwords for shared servers [1][2]. - create_shared_server: This function handles the creation of shared server records [2]. It is responsible for initializing shared server instances, including copying specific configuration attributes such as tunnel ports and keep-alive settings from the owner of the shared server [1][2]. These methods were part of a broader effort to harden pgAdmin 4 against privilege escalation, credential leaks, and data integrity issues by enforcing strict isolation between server owners and other users [2].

💡 Result:
The string "passfile" within the context of SharedServer and data.tags refers to internal configuration attributes managed by pgAdmin [1][2]. Specifically, SharedServer is a model used in pgAdmin to handle server registrations shared across users [1]. Recent architectural updates to pgAdmin have introduced dedicated columns to the SharedServer model, including tags, to ensure feature parity between shared and individual server registrations [1][2]. Regarding the specific terms: - SharedServer data.tags: In the pgAdmin codebase, tags are part of the metadata persisted for SharedServer objects [1][2]. These tags allow users to organize shared servers, and recent changes ensure that non-owner users can interact with these tags (such as reading or updating them) while maintaining correct differential application of changes [1][2]. - passfile: This is a connection parameter used to point pgAdmin to a pgpass file containing database credentials [3]. In a server registration (including SharedServer definitions), you can specify a passfile parameter within the ConnectionParameters JSON block [3][4][5]. This allows the application to authenticate automatically without prompting the user for a password [3]. When configuring passfile for shared servers in pgAdmin's "Server mode" (typically containerized environments), users must ensure the path is accessible to the pgAdmin process [6]. Because pgAdmin in server mode often restricts access to the file system, common practices include mapping a pgpass file into a specific storage location (often inside /var/lib/pgadmin/storage/ or a relative path from the user's home directory) and referencing that path in the servers.json configuration [4][7][5]. The passfile parameter is prioritized by pgAdmin's connection manager to resolve credentials [8].

💡 Result:
In the pgAdmin 4 codebase, specifically within web/pgadmin/browser/server_groups/servers/init.py, the methods get_shared_server and create_shared_server are static methods of the ServerModule class used to manage shared server records in server mode [1][2]. get_shared_server(server, gid) This method retrieves the SharedServer record for the current user. If a record does not exist for the current user and the specified server (identified by osid), it lazily creates one by calling create_shared_server [1]. It uses a query on the SharedServer model filtered by the current user's ID and the server's ID to ensure data isolation, and it handles concurrent requests using database transaction rollbacks if a unique constraint violation occurs [1][3]. create_shared_server(data, gid) This method is responsible for creating a new SharedServer record. It creates a persisted entry in the database that associates a server configuration with a specific user [1]. This mechanism allows pgAdmin to manage user-specific overrides (such as connection parameters or SSH tunnel settings) for shared servers while maintaining the integrity of the original server definition [3][2]. These methods are central to pgAdmin's server-mode architecture, which enables administrators to share server definitions across multiple users while ensuring that sensitive information, such as passwords or SSH tunnel configurations, remains isolated or correctly scoped to the individual user [3][2].

repo:pgadmin-org/pgadmin4 "SharedServer" "server_default" "tags"
💡 Result:
In the pgAdmin 4 codebase, the SharedServer model includes a tags field designed to support feature parity with the standard Server model [1][2]. This allows non-owner users to maintain per-user values (such as tags) via an overlay mechanism, rather than inheriting or having their values suppressed by the owner's configuration [1][2]. Recent updates to pgAdmin 4 have refactored the SharedServer model and its interaction with the server overlay logic [1][2]. Specifically: 1. Persistence and Parity: The SharedServer schema was updated to include persisted columns—including tags, passexec_cmd, passexec_expiration, kerberos_conn, and post_connection_sql—to ensure that shared servers behave consistently for non-owners [1][2]. 2. Overlay Logic: The system handles tag operations by reading from and writing to the SharedServer record for non-owners [1][2]. When a non-owner updates a shared server, the application computes tag differences based on the shared server record (acting as the base) to ensure updates are applied correctly without overwriting existing tags or incorrectly inheriting the owner's tags [1][2]. 3. Default Configuration: In the migration and model definitions, fields like kerberos_conn are initialized using SQLAlchemy's portable boolean literals (e.g., server_default=sa.false) to ensure consistent behavior across different database backends [1][2]. Shared server functionality, including tag management, is a feature of pgAdmin 4's server mode, which allows administrators to share server definitions with other users [3]. Non-owner users see these servers in their browser interface and can interact with them according to defined permissions [3].

repo:pgadmin-org/pgadmin4 "sharedserver_feature_parity" migration
💡 Result:
The sharedserver_feature_parity migration in pgAdmin 4 refers to a database schema update introduced to enhance the consistency and security of the Shared Server feature, particularly in server (multi-user) mode [1]. Key aspects of this migration include: Purpose and Functionality: The migration was designed to achieve feature parity for Shared Servers by ensuring that non-owner users have independent control over specific server parameters [1]. Previously, certain settings might have been inherited from the server owner; the migration allows non-owner users to maintain their own values for fields such as passexec_cmd, passexec_expiration, kerberos_conn, tags, and post_connection_sql [1]. It also enforces security by implementing write guards, preventing non-owners from modifying specific sensitive fields while allowing them to configure others (like post_connection_sql) that run under their own credentials [1]. Database Impact: This migration bumped the schema version (to 51) and added several columns to the SharedServer model while removing obsolete columns (such as db_res) [1]. It was part of a broader effort to harden data isolation, particularly in server mode, to address vulnerabilities related to cross-user data access [2][3]. Upgrade Considerations: Users upgrading to versions containing this migration (such as v9.15) have experienced issues during the migration process, including potential duplication of server groups and challenges with credentials [4]. The complexity of these changes means that users should ensure they have backups of their configuration database (pgadmin4.db) before performing upgrades, as downgrades often require restoring from a backup file (e.g., pgadmin4.db.prev.bak) due to the non-backward-compatible nature of these schema changes [5][4]. For general management of server configurations, including migration between instances, pgAdmin provides built-in import/export functionality via the setup.py CLI tool, which allows users to export server definitions to JSON and import them into other installations [6][7].

https://github.com/pgadmin-org/pgadmin4/pull/9830/files "passfile" "tags"
💡 Result:
In pgAdmin 4, the "passfile" parameter is used to specify the file path to a PostgreSQL password file (.pgpass), which allows for authentication without manually providing a password [1][2][3][4]. This functionality relies on the libpq library [4]. Regarding the specific context of Pull Request #9830 and recent updates: 1. Recent Security Enhancements: Pull Request #9830 (merged April 2026) focused on hardening server-mode deployments, specifically addressing data isolation, credential leaks, and privilege escalation vulnerabilities [5]. It enforced stricter access checks on various server operations to prevent unauthorized access in shared server environments [5]. 2. Precedence and Behavior: As of pgAdmin 4 version 9.16, the handling of credentials has been updated to prioritize the passfile [6]. If a server connection is configured with both an external password-exec command and a passfile, pgAdmin now defaults to using the passfile and ignores the password-exec command, logging a warning when this conflict occurs [6]. 3. Configuration and Usage: - In server import/export JSON files, the parameter is typically represented as "passfile" within the "ConnectionParameters" object [2]. - When running in pgAdmin's server mode, especially in containerized environments (like Docker), paths for the passfile can sometimes be interpreted relative to the user's storage directory unless specifically configured otherwise [7]. - Users should ensure the.pgpass file adheres to PostgreSQL security requirements, typically requiring permissions set to 0600 (read/write by owner only) to be accepted by libpq [3][7]. top_results: [5][2][6][3][4][7]

💡 Result:
The GitHub commit e4edcf2, associated with pull request #9835, implements a migration for the SharedServer feature in pgAdmin 4 to improve feature parity and security [1][2]. Key details of this migration and the associated changes include: Feature Parity and Schema Updates: The migration adds five columns to the SharedServer model: passexec_cmd, passexec_expiration, kerberos_conn, tags, and post_connection_sql [1][2]. These additions allow non-owner users to maintain their own per-user values for these fields rather than inheriting them from the owner [1][2]. Additionally, the migration drops the db_res column, which was identified as unused by non-owners [1][2]. Security and Write Guards: To prevent unauthorized modification of sensitive configurations, the commit introduces an _owner_only_fields guard [1]. This mechanism blocks non-owners from setting sensitive fields (specifically passexec_cmd, passexec_expiration, post_connection_sql, db_res, and db_res_type) via the API [1][2]. Deployment Warning: Because this migration includes destructive schema changes (dropping a column), it has been associated with deployment hazards in containerized environments (such as Kubernetes) [3]. Specifically, if an environment uses a RollingUpdate deployment strategy where an older container version and a newer container version share a data volume, the newer version may execute the migration and drop the column while the older version still expects it to exist, causing runtime errors (e.g., sqlite3.OperationalError) [3]. Official guidance recommends using a Recreate deployment strategy instead of RollingUpdate and ensuring init containers do not run a newer version of the image than the main application container [3].

Check the original request fields before membership normalization.
validate_request expands a valid rolmembers request with internal keys such as rol_members_list and rol_members_revoked_list before this check runs. Therefore, every valid membership-only update fails the subset test and returns 403.
Record the client-supplied key set before _validate_rolemembers mutates data. Use that set for this authorization check. Add a request-level regression test for an ADMIN OPTION update containing only rolmembers.

Invalidate the cached async cursor for the temporary-cursor path.
poll() reads self.__async_cursor, but this branch only replaces the local cur. The cached server cursor remains available. A subsequent poll() can read its previous result and restore stale column metadata.
Define the post-transaction poll() result, then invalidate or replace self.__async_cursor before execution. Extend the regression test to call poll() after execute_void() and verify that it cannot restore the prior result state.

cursor, and ensure the subsequent poll() returns the defined post-transaction
empty result without restoring stale metadata or rows. Extend the existing
regression test for execute_void() to call poll() afterward and verify the prior
result state is not restored.

What this is
Since 9.15, standard (non-admin) users connecting to a pre-configured shared server (
servers.json,shared: true) no longer see the server's tags, and no longer get itspassfileconnection parameter applied — they're prompted for a password instead. Admin users are unaffected.Both are the same root cause:
ServerModule.create_shared_server(), which materialises a standard user's ownSharedServercopy of the owner's server, was silently dropping fields that used to be copied verbatim.9a76ed80b(fix: enforce data isolation and harden shared servers in server mode #9830, 9.15 data-isolation hardening) introducedSENSITIVE_CONN_KEYSand started stripping all of it — includingpassfile— fromconnection_params.passfileisn't a personal secret path likesslcert/sslkey; it's how a shared server's owner lets every user of that server authenticate automatically, so it needs to be copied like any other connection parameter, whilst the genuine SSL client cert/key paths stay stripped.e4edcf225(fix: SharedServer feature parity columns and write guards #9835) addedtagsto theSharedServermodel but seeded it astags=Noneat creation instead of copying the owner's value.Fixes #10136, fixes #10137.
Fix
create_shared_server():tagsnow copied from the owner's server like the other copied fields (bgcolor,fgcolor,service, etc.);passfileexcluded from theSENSITIVE_CONN_KEYSstrip.The ownership/write boundary from #9830/#9835 is untouched — standard users still can't edit the owner's
Serverrow, they just read the same connection parameters an admin configured, which is what a shared server is for.Test plan
