Lack of input filtering leads to an XSS vector in the HTML filter code related to data URLs in img tags.

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.
