Name of the Vulnerable Software and Affected Versions Regular Labs Sourcerer versions prior to 14.0.0
Description An unauthenticated remote code execution (RCE) issue exists because the software processes {source} blocks found in the final rendered HTML of Joomla without reliably determining the origin of the code. This allows for the execution of arbitrary code through unverified reflected user input.
Recommendations Update Regular Labs Sourcerer to version 14.0.0 or later.
