CVE-2025-60511

Medium severity, CVSS 4.3. EPSS: 0.2% chance of exploitation in the next 30 days.

Moodle OpenAI Chat Block plugin 3.0.1 (2025021700) suffers from an Insecure Direct Object Reference (IDOR) vulnerability due to insufficient validation of the blockId parameter in /blocks/openai_chat/api/completion.php. An authenticated student can impersonate another user's block (e.g., administrator) and send queries that are executed with that block's configuration. This can expose administrator-only Source of Truth entries, alter model behavior, and potentially misuse API resources.
