Exploitation conditions

  • Applications using pg_insert(), pg_update(), pg_select() or pg_delete() with untrusted input

Remediation

Upgrade to 8.2.33, 8.3.33, 8.4.24, 8.5.9 or a later release of your branch. If your branch is end-of-life, move to a supported branch. Distribution packages may carry a backported fix under an older version number; confirm with your vendor's security tracker.

A version number alone cannot prove patch status. Linux distributions and hosting providers often backport security fixes without changing the version. Check your vendor’s changelog.
