{"id":"CVE-2026-104055","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-104055","generatedAt":"2026-10-27T23:59:04.993Z","title":"The postgresql-operator charm runs a Prometheus postgres_exporter to collect database metrics using a dedicated \"monitoring\" PostgreSQL user.","description":"The postgresql-operator charm runs a Prometheus postgres_exporter to collect database metrics using a dedicated \"monitoring\" PostgreSQL user. On database connection errors, the exporter writes the monitoring user's password in cleartext to its logs. Any actor able to read those logs can recover the password, which grants read-only pg_monitor access to PostgreSQL.
