## FAQ

### What does this mean?

Breadcrumb trails can show information from unpublished parent taxonomy terms that a viewer should not be able to see. The module does not properly check view access on parent terms before rendering breadcrumb segments.

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

Versions before 2.0.11 are in scope, but only when the "Add parent hierarchy" (term_hierarchy) setting is enabled and at least one term has an unpublished parent term. Check the installed Easy Breadcrumb version on the Drupal extensions page and whether that setting is enabled in the module's configuration.

### What should I do about it?

Upgrade Easy Breadcrumb to 2.0.11, which contains the fix. No workaround is listed in the advisory.

### 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.
