Mitigatie en Workaroundswordt vertaald…
The primary mitigation for CVE-2026-5395 is to immediately upgrade the Fluent Forms plugin to version 6.2.1 or later. If upgrading is not feasible due to compatibility issues or breaking changes, consider temporarily restricting access to the exportEntries function through WordPress's built-in access control mechanisms. While not a complete fix, this can limit the potential impact. Monitor WordPress logs for suspicious activity related to database access or form exports. After upgrading, confirm the fix by attempting to access form submissions from a user account without the necessary permissions; access should be denied.
Hoe te verhelpen
Update naar versie 6.2.1, of een nieuwere gepatchte versie
