CVE-2022-39231
LOWParse Server subject to Improper Authentication allowing Auth adapter app ID validation to be circumvented
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

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 4.10.16, or from 5.0.0 to 5.2.6, validation of the authentication adapter app ID for Facebook and Spotify may be circumvented. Configurations which allow users to authenticate using the Parse Server authentication adapter where appIds is set as a string instead of an array of strings authenticate requests from an app with a different app ID than the one specified in the appIds configuration. For this vulnerability to be exploited, an attacker needs to be assigned an app ID by the authentication provider which is a sub-set of the server-side configured app ID. This issue is patched in versions 4.10.16 and 5.2.7. There are no known workarounds.

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 4.10.16 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-39231 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-2022-39231 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-2022-39231. 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-2022-39231 in your dependencies?
O3 detects CVE-2022-39231 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
