Background
pgAdmin 4 is a popular open-source administration and development platform for PostgreSQL, allowing users to manage databases through a web interface. It supports various features such as server management, query execution, and debugging. However, it has been found to have an authorization vulnerability in its server mode, affecting several modules including Server Groups, Servers, Shared Servers, Background Processes, and Debugger.
Vulnerability Detail
The vulnerability arises from multiple endpoints that fetch user-owned objects without filtering by the requesting user's identity. This flaw allows an authenticated user to access another user's private servers, server groups, background processes, and debugger function arguments by merely guessing object IDs. Additionally, the Shared Servers feature has serious issues, including credential leakage, privilege escalation, and owner-data corruption due to writable fields accessible by non-owners. The vulnerability is classified as critical with a CVSS score of 9.9, indicating severe potential ramifications.
