DescriptionCVE.org

phpMyFAQ before 4.1.8 enforces incorrect permission checks on admin content pages, allowing lesser-privileged editors to read draft and inactive content. Attackers with only add permissions can access news edit and FAQ translate endpoints to view unpublished content invisible to the public.

AnalysisAI

Incorrect authorization (CWE-863) in phpMyFAQ before 4.1.8 allows authenticated low-privileged editors to read draft and inactive content that is intentionally withheld from public view. Users holding only 'add' permissions can directly invoke the news-edit and FAQ-translate admin endpoints, bypassing the intended role separation and exposing unpublished material. …
