CVE-2026-21625

User provided uploads to the Easy Discuss component for Joomla aren't properly validated.

MEDIUM 4.8EPSS 0.37%

Does this matter?

Lower severity and a low EPSS score (0.37%). Track it; it rarely justifies an emergency change on its own.

Description

User provided uploads to the Easy Discuss component for Joomla aren't properly validated. Uploads are purely checked by file extensions, no mime type checks are happening.
