Medium severity, CVSS 4.3. EPSS: 0.3% chance of exploitation in the next 30 days.

LearnPress WordPress Plugin before 4.4.6 contains a broken object-level authorization vulnerability that allows authenticated attackers with the Instructor role to add answers to quiz questions owned by other instructors by exploiting a missing ownership check on the question answer insert path. Attackers can supply arbitrary question identifiers during answer insertion, bypassing instructor-boundary restrictions to persistently modify quiz content across courses they do not own.
