Detailsinfo

A vulnerability classified as critical was found in pgAdmin 4 up to 9.14. This vulnerability affects an unknown part. The manipulation of the argument passexec_cmd/passexec_expiration/db_res/db_res_type with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is available at github.com. This vulnerability was named CVE-2026-7813 since 05/04/2026. The exploitation appears to be easy. The attack can be initiated remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1068 by the MITRE ATT&CK project.

Upgrading to version 9.15 eliminates this vulnerability.
