## FAQ

### What does this mean?

The module does not sufficiently sanitize the attributes it applies to menu link container elements, so stored script can be injected through them, which is cross-site scripting. The attacker needs a role with the 'Administer menus and menu links' and 'Use menu link attributes' permissions.

### Am I affected, and how do I check?

Menu Link Attributes versions before 1.8.0 are affected. The default configuration is not affected, and the issue requires an unsafe container attribute to already be configured by a user with the restricted 'Administer menu link attributes' permission. Check your installed module version and whether any such container attribute has been configured.

### What should I do about it?

Update Menu Link Attributes to 8.x-1.8 (version 1.8.0), which contains the fix.

### Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.
