CVE-2022-41954 has a CVSS score of 3.3/10, rated LOW. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2022-41954?

CVE-2022-41954 affects the following packages: net.sf.mpxj:mpxj (Maven), net.sf.mpxj (NuGet), net.sf.mpxj-for-csharp (NuGet), net.sf.mpxj-for-vb (NuGet), mpxj (PyPI). Ecosystems affected: Maven, NuGet, PyPI.

How do I fix CVE-2022-41954?

Update net.sf.mpxj:mpxj to 10.14.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-41954 is resolved across your whole dependency graph.

How do I detect CVE-2022-41954 in my Maven, NuGet, PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for net.sf.mpxj:mpxj. 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.

How do I mitigate CVE-2022-41954 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2022-41954?

O3 pinpoints whether CVE-2022-41954 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2022-41954 actively exploited in the wild?

No public exploit code has been indexed for CVE-2022-41954 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2022-41954?

CVE-2022-41954 has an EPSS (Exploit Prediction Scoring System) score of 0.2%, placing it in the 11th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

When was CVE-2022-41954 published, and has it been updated?

CVE-2022-41954 was published on November 25, 2022 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven, NuGet packages — download data is not available via public APIs for these ecosystems.

Description

MPXJ is an open source library to read and write project plans from a variety of file formats and databases. On Unix-like operating systems (not Windows or macos), MPXJ's use of File.createTempFile(..) results in temporary files being created with the permissions -rw-r--r--. This means that any other user on the system can read the contents of this file. When MPXJ is reading a schedule file which requires the creation of a temporary file or directory, a knowledgeable local user could locate these transient files while they are in use and would then be able to read the schedule being processed by MPXJ. The problem has been patched, MPXJ version 10.14.1 and later includes the necessary changes. Users unable to upgrade may set java.io.tmpdir to a directory to which only the user running the application has access will prevent other users from accessing these temporary files.
