Synopsis

A PHP application running on the remote web server is affected by multiple vulnerabilities.

Description

According to its self-reported version, the instance of Joomla! running on the remote web server is 4.0.x prior to 5.4.9 or 6.0.x prior to 6.1.4. It is, therefore, affected by multiple vulnerabilities.

- Joomla! Core - [20260905] - Core - Arbitrary directory deletion via cache purge action in Joomla 4.0.0-5.4.8, 6.0.0-6.1.3 - An improper validation of the cache group name allowed path traverals in the file storage of the caching layer, resulting in arbitrary directory deletions. (CVE-2026-90915)

- Joomla! Core - [20260913] - Core - Improper ACL checks for varous webservice edit tasks in Joomla 4.0.0-5.4.8, 6.0.0-6.1.3 - An improper access check allows unauthorized users to perform edit actions on otherwise uneditable items. (CVE-2026-92226)

- Joomla! Core - [20260914] - Core - MFA Authentication Bypass through rememberme cookies in Joomla 4.0.0-5.4.8, 6.0.0-6.1.3 - The premature issuance of an rememberme cookie leads to a MFA bypass vulnerability. (CVE-2026-92227)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Joomla! version 5.4.9 / 6.1.4 or later.
