CVE-2022-23793Public exploitNetwork attack vector

Arbitrary file write via unchecked TAR paths

Published Mar 30, 2022 · Updated Feb 25, 2026

Path traversal in Joomla! CMS 3.0.0 through 3.10.6 and 4.0.0 through 4.1.0 allows remote authenticated users to write arbitrary files. Joomla Archive Package before 1.1.12 and 2.0.0 writes Tar::extract entry data to a cleaned joined path without confirming that it remains under the requested destination. Joomla! core exploitation requires administrator privileges; third-party callers can expose the write under different access controls.
