This can occur when relying on the password to validate a self-signed cert, e.g., MariaDB's zero-configuration TLS.\n\n## Impact\n\nAn attacker who can deploy a man-in-the-middle MySQL proxy presenting any self-signed certificate can capture the plaintext database password of a client that:\n\n- uses `SslMode = VerifyCA` or `VerifyFull`, and\n- does not use the `SslCa` connection string option, and\n- uses a non-empty password.\n\nThe attacker completes the TLS handshake with its own cert, requests a clear-text password authentication scheme (`mysql_clear_password`, or forces the `caching_sha2_password`/`sha256_password` clear-text fallback), and receives the password before the fingerprint check rejects the connection, defeating the man-in-the-middle protection `VerifyFull` is expected to provide. \n\nNot affected: a configured CA (`SslCa`), CA-validated TLS, local connecti","public_affected_ranges":["< 2.6.1"]}],"null_published_at":"2026-10-31T22:13:27.120Z","source_updated_at":"2026-10-28T19:49:45.000Z","source_disclosed_at":"2026-10-28T19:49:44.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-10-31T21:56:36.327Z"}],"next_cursor":null,"snapshot_revision":"42594"}
