drupal/easy_breadcrumb is vulnerable to Information disclosure
42
Medium Risk
This Affects:
drupal/easy_breadcrumbTL;DR
The Easy Breadcrumb module builds breadcrumb trails for taxonomy term hierarchies. When the "Add parent hierarchy" setting is enabled, affected versions add parent terms to the trail without checking whether the current user can view them, so an unpublished parent term's title can appear for visitors who should not see that term. Exploitation requires that setting to be enabled and at least one unpublished term in the parent hierarchy. The fix omits parent terms the current user is not allowed to view.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range, the "Add parent hierarchy" setting is enabled, and a term in the parent hierarchy is unpublished.
