OSVDRUPAL-CONTRIB-2026-051 No score
This module enables you to collect feedback from your site visitors on content pages, presenting Yes/No buttons and providing dashboards for administrators to review the responses.
The module doesn't sufficiently sanitize several administrator-configured response messages (the "Yes response", "No response", and the custom text shown on a "No" answer) under the scenario where those settings contain HTML or script markup, which is then emitted as raw HTML in the feedback response shown to visitors.
This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer admin feedback".
