CVE-2026-7813 pgadmin.org CVE debrief

Who should care

Organizations running pgAdmin 4 in server mode with multiple authenticated users; database administrators managing shared server configurations; security teams monitoring for lateral movement and privilege escalation in database management tools; compliance officers responsible for access control and data segregation requirements.

Technical summary

The vulnerability stems from missing authorization checks on endpoints retrieving user-owned objects. In server mode, object IDs were not validated against the requesting user's identity, allowing authenticated users to enumerate and access other users' Server Groups, Servers, Background Processes, and Debugger data through predictable ID sequences. The Shared Servers feature introduced additional attack surface: passexec_cmd (a shell command executed during connection establishment) was both readable and writable by non-owners, enabling credential theft and arbitrary command execution in the owner's security context. Owner-only fields lacked proper write guards, and fields without per-user persistence caused destructive cross-user modifications. The remediation architecture introduces a server_access module for centralized authorization, UserScopedMixin for consistent user-scoped queries, HTTP 410 denial responses, field suppression for non-owners, and explicit write guards on sensitive owner-only attributes.

Defensive priority

CRITICAL

Recommended defensive actions

• Upgrade pgAdmin 4 to version 9.15 or later to obtain the centralized access control fixes
• Review server mode deployments for unauthorized access patterns in audit logs, particularly around Server Groups, Shared Servers, Background Processes, and Debugger modules
• Audit existing Shared Server configurations for potential credential exposure or unauthorized modifications to passexec_cmd, passfile, SSL keys, and other sensitive fields
• Verify that non-owner users cannot view or modify owner-only fields including passexec_cmd, passexec_expiration, db_res, and db_res_type
• Monitor for HTTP 410 responses from connection_manager as indicators of access control enforcement
• Review SQLAlchemy session handling for data persistence issues affecting kerberos_conn, tags, and post_connection_sql fields

Evidence notes

Authorization bypass via missing user-scoped filtering on object retrieval endpoints. Credential leakage and privilege escalation in Shared Servers feature through writable passexec_cmd field. Data corruption via SQLAlchemy session mutations affecting fields without per-user persistence.
