GHSA-385f-vgq7-8hhx
MEDIUMGHSA-385f-vgq7-8hhx is a medium-severity (CVSS 4.3) CWE-862 vulnerability in moodle/moodle. O3 Security confirms whether GHSA-385f-vgq7-8hhx is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

moodle/moodle🐘moodle/moodle🐘moodle/moodleReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.
Description
The H5P activity attempts report did not filter by groups, which in separate groups mode could reveal information to non-editing teachers about attempts/users in groups they should not have access to.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for moodle/moodle. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update moodle/moodle to 3.9.17 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-385f-vgq7-8hhx is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-385f-vgq7-8hhx is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-385f-vgq7-8hhx. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-385f-vgq7-8hhx in your dependencies?
O3 detects GHSA-385f-vgq7-8hhx across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
