GHSA-j822-x5gg-5r56
MEDIUMGHSA-j822-x5gg-5r56 is a medium-severity (CVSS 6.5) CWE-862 vulnerability in moodle/moodle. O3 Security confirms whether GHSA-j822-x5gg-5r56 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Moodle allows users to retrieve information they did not have permission to access

Description
A flaw was found in Moodle. Dynamic tables did not enforce capability checks, which resulted in users having the ability to retrieve information they did not have permission to access.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐘Packagist | moodle/moodle | all versions | 4.1.13 |
| 🐘Packagist | moodle/moodle | ≥ 4.2.0-beta&&< 4.2.10 | 4.2.10 |
| 🐘Packagist | moodle/moodle | ≥ 4.3.0-beta&&< 4.3.7 | 4.3.7 |
| 🐘Packagist | moodle/moodle | ≥ 4.4.0-beta&&< 4.4.3 | 4.4.3 |
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 4.1.13 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-j822-x5gg-5r56 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-j822-x5gg-5r56 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-j822-x5gg-5r56. 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-j822-x5gg-5r56 in your dependencies?
O3 detects GHSA-j822-x5gg-5r56 across Packagist dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
