Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The jsoup package (Maven org.jsoup:jsoup) versions 1.14.3 up to 1.23.1 are affected. When a custom Safelist permits raw-text elements, malformed HTML with a tag name ending in a control character may be sanitized incorrectly, so content meant to stay as text can be emitted as active markup, potentially enabling cross-site scripting. Upgrade to jsoup 1.23.1. Until then, do not permit raw-text elements in custom Safelists used to clean untrusted HTML.
