This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the Script Blocking feature to be enabled, and the exploit chain depends on an attacker submitting two coordinated comments — one embedding event-handler syntax inside an allowed <code> element and one placing the deterministic ___noise___ restoration key inside an allowed <abbr title=""> attribute — with the key offset confirmable via an unauthenticated wpconsent_debug=1 request. ## Remediation Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
