parse-servernpmDescription
Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. In versions prior to 4.10.15, or 5.0.0 and above prior to 5.2.6, a user can write to the session object of another user if the session object ID is known. For example, an attacker can assign the session object to their own user by writing to the user field and then read any custom fields of that session object. Note that assigning a session to another user does not usually change the privileges of either of the two users, and a user cannot assign their own session to another user. This issue is patched in version 4.10.15 and above, and 5.2.6 and above. To mitigate this issue in unpatched versions add a beforeSave trigger to the _Session class and prevent writing if the requesting user is different from the user in the session object.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for parse-server. 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 parse-server to 4.10.15 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-39225 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-2022-39225 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-2022-39225. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2022-39225 in your dependencies?
O3 detects CVE-2022-39225 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
