CVE-2025-48382
Fix: codelibs/fess@25b2009CVE-2025-48382 is a CWE-732 vulnerability in org.codelibs.fess:fess. O3 Security confirms whether CVE-2025-48382 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Fess has Insecure Temporary File Permissions
Real-World Exposure
org.codelibs.fess:fessReal-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.

Detection & mitigation playbook
Open-source dependencyDetect
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.
Fix
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.
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-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.
Tailored to CVE-2025-48382. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
