URL Redirection to Untrusted Site ('Open Redirect') vulnerability in the HTML5 scrubber in rrrene html_sanitize_ex allows an unauthenticated remote… (CVE-2026-66370)CVE-2026-66370 0 CVE-2026-66370 is an Open Redirect vulnerability in the HTML5 scrubber component of the html_sanitize_ex library. It allows an unauthenticated remote attacker to manipulate form input elements in sanitized HTML to redirect form submissions to an attacker-controlled external URL. The vulnerability arises because the scrubber does not validate the scheme of URLs in the form and formaction attributes, allowing cross-origin redirection. The attacker cannot inject new forms or buttons, so the attack requires the presence of an existing form with an id on the page. No script execution is possible through this vulnerability.
