Pgadmin: >> Pgadmin 4 >> 6.0 Security Vulnerabilities
Authorization vulnerability in pgAdmin 4 server mode affecting Server Groups, Servers, Shared Servers, Background Processes, and Debugger modules.
Multiple endpoints fetched user-owned objects without filtering by the requesting user's identity. An authenticated user could access another user's private servers, server groups, background processes, and debugger function arguments by guessing object IDs.
Additionally, the Shared Servers feature contained multiple issues including credential leakage (passexec_cmd, passfile, SSL keys), privilege escalation via writable passexec_cmd (a shell command executed when establishing the connection) allowing arbitrary command execution in the owner's process context, and owner-data corruption via SQLAlchemy session mutations. Several owner-only fields (passexec_cmd, passexec_expiration, db_res, db_res_type) were writable by non-owners through the API, and additional fields (kerberos_conn, tags, post_connection_sql) lacked per-user persistence so non-owner edits mutated the owner's record.
Fix centralises access control via a new server_access module, scopes all user-owned models with a UserScopedMixin, returns HTTP 410 from connection_manager when access is denied in server mode, suppresses owner-only fields for non-owners across the merge / API response / ServerManager paths, and adds an explicit owner-only write guard. The remediation landed in two pull requests; both are referenced.
This issue affects pgAdmin 4: before 9.15.

pgAdmin versions up to 9.10 are affected by a Remote Code Execution (RCE) vulnerability that occurs when running in server mode and performing restores from PLAIN-format dump files. This issue allows attackers to inject and execute arbitrary commands on the server hosting pgAdmin, posing a critical risk to the integrity and security of the database management system and underlying data.

Remote Code Execution security vulnerability in pgAdmin 4 (Query Tool and Cloud Deployment modules).
The vulnerability is associated with the 2 POST endpoints; /sqleditor/query_tool/download, where the query_commited parameter and /cloud/deploy endpoint, where the high_availability parameter is unsafely passed to the Python eval() function, allowing arbitrary code execution.
This issue affects pgAdmin 4: before 9.2.
