CVE-2026-76605Network attack vector

Unauthenticated code execution via image eval flag

Published Aug 22, 2026 · Updated Aug 22, 2026

Code injection in Fabrik before 4.7.3 allows remote attackers to execute arbitrary PHP code through a crafted image element. Fabrik identifies the vulnerable locus as the image element's eval flag but has not published the exact input-to-eval data flow. No authentication or user interaction is required, and successful exploitation runs code in the Joomla PHP process context.
