SCA: security update for typo3/cms, typo3/html-sanitizer (GHSA-hvwx-qh2h-xcfj)

medium Tenable Cloud Security Plugin ID 415965

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- HTML sanitizer is written in PHP, aiming to provide XSS-safe markup based on explicitly allowed tags,
attributes and values. In versions prior to 1.5.0 or 2.1.1, malicious markup used in a sequence with
special HTML CDATA sections cannot be filtered and sanitized due to a parsing issue in the upstream
package masterminds/html5. This allows bypassing the cross-site scripting mechanism of typo3/html-
sanitizer. The upstream package masterminds/html5 provides HTML raw text elements (`script`, `style`,
`noframes`, `noembed` and `iframe`) as DOMText nodes, which were not processed and sanitized further. None
of the mentioned elements were defined in the default builder configuration, that's why only custom
behaviors, using one of those tag names, were vulnerable to cross-site scripting. This issue has been
fixed in versions 1.5.0 and 2.1.1. (CVE-2022-23499)
