Summary

CVE-2023-38500 is a vulnerability that affects TYPO3 HTML Sanitizer versions 1.0.0 and prior to versions 1.5.1 and 2.1.2. The vulnerability allows for the bypassing of the cross-site scripting mechanism of TYPO3 HTML Sanitizer due to an encoding issue in the serialization layer, specifically when malicious markup is nested in a `noscript` element that is not encoded correctly. Although `noscript` is disabled by default, it may have been enabled in custom scenarios. The issue can be remediated by updating to versions 1.5.1 or 2.1.2, which fix the problem. This vulnerability poses a medium risk to organizations as it requires user interaction and can lead to low integrity and confidentiality impacts on affected systems, potentially allowing for cross-site scripting attacks (CWE-79).
