CVE-2026-64796Network attack vector

Remote code execution via inconsistent permission checks

Published Jul 22, 2026 · Updated Jul 22, 2026

Improper access control in Regular Labs Sourcerer 1.0.0 through 12.2.8 allows remote attackers to execute injected PHP in Joomla. The article-processing and include-path checks fail to require both owners' configured permissions, confine PHP includes, or reject executable script and style variants. Reachability depends on content reaching Sourcerer processing, and successful PHP execution runs with the Joomla server process's privileges.
