XSS vulnerability in 'disabled module' error template

This security advisory fixes a vulnerability in eZ Publish Legacy, and we recommend that you install it as soon as possible if you are using Legacy via the LegacyBridge.

To install, use Composer to update to one of the "Resolving versions" mentioned above, or apply this patch manually:
