Technical Analysis
CVE-2026-82023 is a broken object-level authorization vulnerability in the LearnPress WordPress Plugin prior to version 4.4.6. Authenticated attackers with the Instructor role can exploit a missing ownership verification on the question answer insertion path to supply arbitrary question identifiers. This bypasses instructor-boundary restrictions and allows persistent modification of quiz answers for questions belonging to other instructors, potentially compromising quiz integrity across multiple courses.
Potential Impact
The vulnerability allows authenticated instructors to modify quiz answers for questions they do not own, potentially undermining the integrity of quizzes and course content managed by other instructors. This could lead to unauthorized changes in educational assessments but does not directly impact system confidentiality, availability, or escalate privileges beyond the Instructor role.
