Wagtail CMS Stored XSS Vulnerabilities

Stored XSS in Wagtail's simple_translation module allows authenticated admin users to inject malicious JavaScript through specially-crafted page titles that executes when other admins perform translation actions, potentially compromising their credentials. The vulnerability affects Wagtail versions prior to 6.3.8, 7.0.6, 7.2.3, and 7.3.1, and requires admin-level access to exploit, limiting exposure to internal threats. Patches are available for all affected versions.

The vulnerability affects Wagtail versions prior to 6.3.8, 7.0.6, 7.2.3, and 7.3.1, with patches now available.
