Capgo before 12.128.2 contains an information disclosure vulnerability in the unauthenticated /replication endpoint that exposes internal PostgreSQL replication telemetry including slot names and WAL LSN positions. Attackers can access this endpoint without authentication to retrieve sensitive infrastructure details such as replication slot names, confirmed_flush_lsn, restart_lsn values, and database error messages for reconnaissance purposes.
