Synopsis

Joomla! 6.x < 6.0.2 Multiple Vulnerabilities

Description

According to its self-reported version, the instance of Joomla! running on the remote web server is 3.9.x prior to 5.4.2, or 6.x prior to 6.0.2. It is, therefore, affected by multiple vulnerabilities.

 - Lack of input filtering leads to an XSS vector in the HTML filter code related to data URLs in img tags. (CVE-2025-63082)

 - Lack of output escaping leads to a XSS vector in the pagebreak and pagenavigation plugins. (CVE-2025-63083)

Note that the scanner has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update to Joomla! version 6.0.2 or latest.
