CVE-2026-73327

Name of the Vulnerable Software and Affected Versions Joomla version 6.1.1

Description A path traversal issue exists in the com joomlaupdate extension. A Super User can be tricked into extracting a specially crafted archive containing absolute paths or directory traversal sequences in ZIP entry filenames. By providing these malicious names to the extract.php extraction routine, files can be written outside the intended destination root, which allows for persistent remote code execution through the placement of PHP files.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
