Security readout for executives and security teams
This issue affects Drupal sites using the Password Policy contributed module when a password policy uses the username constraint. A crafted username imported from an external source could place script or HTML into unspecified administration pages, creating an XSS risk for administrators. Exposure appears limited to Drupal installations running the Password Policy module in affected 6.x-1.x or 7.x-1.x versions, with a password policy using the username constraint and usernames imported from an external source. Treat as a targeted maintenance priority for Drupal estates, especially where administrators manage externally imported users. It is not KEV-listed in the provided data, but administrator-facing XSS can create meaningful account and site-management risk. Mitigation focus: Upgrade Password Policy module to 6.x-1.11, 7.x-1.11, or later.; Check Drupal advisory guidance for any version-specific remediation notes.; Identify policies using the username constraint and review their necessity..
