No CVSS score has been assigned to CVE-2025-48382 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2025-48382?

CVE-2025-48382 affects the following packages: org.codelibs.fess:fess (Maven). Ecosystems affected: Maven.

How do I fix CVE-2025-48382?

Update org.codelibs.fess:fess to 14.19.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-48382 is resolved across your whole dependency graph.

How do I detect CVE-2025-48382 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.codelibs.fess:fess. 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-2025-48382 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-2025-48382?

O3 pinpoints whether CVE-2025-48382 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-2025-48382 actively exploited in the wild?

No public exploit code has been indexed for CVE-2025-48382 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-2025-48382?

CVE-2025-48382 has an EPSS (Exploit Prediction Scoring System) score of 0.1%, placing it in the 3th 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-2025-48382 published, and has it been updated?

CVE-2025-48382 was published on May 27, 2025 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 packages — download data is not available via public APIs for these ecosystems.

Description

Fess is a deployable Enterprise Search Server. Prior to version 14.19.2, the createTempFile() method in org.codelibs.fess.helper.SystemHelper creates temporary files without explicitly setting restrictive permissions. This could lead to potential information disclosure, allowing unauthorized local users to access sensitive data contained in these files. This issue primarily affects environments where Fess is deployed in a shared or multi-user context. Typical single-user or isolated deployments have minimal or negligible practical impact. This issue has been patched in version 14.19.2. A workaround for this issue involves ensuring local access to the environment running Fess is restricted to trusted users only.
