CVE-2026-79615Network attack vector

Contributor-level answer-key disclosure via missing ownership check

Published Aug 28, 2026 · Updated Aug 28, 2026

IDOR in Quiz and Survey Master before 11.2.4 allows remote authenticated users to read other authors’ quiz questions and answer keys. A REST API route returns question-bank entries selected by quiz identifier without verifying that the requesting Contributor owns or may access the referenced quiz. Contributor-level access is sufficient; disclosure is limited to questions, hints, and correct answer keys from other users’ quizzes.
