Sentry Access Control Vulnerabilities
2026-03-18
Cross-course privilege escalation in Moodle Mod Customcert allows authenticated teachers with certificate management rights in any course to read and modify certificate data across the entire Moodle installation due to missing context validation in the editelement callback and save_element web service. An attacker with mod/customcert:manage permissions in a single course can exploit this to disclose sensitive certificate information from other courses or tamper with their certificate elements. Versions 4.4.9 and 5.0.3 patch the vulnerability, but no patch is currently available for affected versions.
An Insecure Direct Object Reference (IDOR) vulnerability exists in Sentry versions prior to 26.1.0 within the GroupEventJsonView endpoint, allowing attackers to access event data across different organizations without proper authorization checks. This information disclosure vulnerability enables cross-organization data leakage where an authenticated attacker with access to one organization can enumerate and retrieve sensitive error tracking and performance monitoring data belonging to other organizations. The vulnerability has been patched in version 26.1.0, and a proof-of-concept is available via the referenced GitHub Security Lab advisory.
