Vulnerability Summary

WordPress Core's HTML API WP_HTML_Tag_Processor::set_modifiable_text() (since 6.7.0) used an incomplete comment-closer guard (/--!?>/) that missed the '-?>' abrupt-closing form, allowing text set into an HTML comment node to terminate the comment early. This is developer-facing hardening; there is no first-party sink that turns it into a direct vulnerability. Impact is realized only in plugin/theme code that round-trips attacker-controlled text through the HTML API into a comment node.
