CVE-2022-36031
MEDIUMCVE-2022-36031 is a medium-severity (CVSS 6.5) CWE-755 vulnerability in directus. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether CVE-2022-36031 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
directusnpmDescription
Directus is a free and open-source data platform for headless content management. The Directus process can be aborted by having an authorized user update the filename_disk value to a folder and accessing that file through the /assets endpoint. This vulnerability has been patched and release v9.15.0 contains the fix. Users are advised to upgrade. Users unable to upgrade may prevent this problem by making sure no (untrusted) non-admin users have permissions to update the filename_disk field on directus_files.
Affected Packages

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for directus. 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 directus to 9.15.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-36031 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 CVE-2022-36031 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 CVE-2022-36031. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
