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.
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
Summary
Fess (an open-source Enterprise Search Server) creates temporary files without restrictive permissions, which may allow local attackers to read sensitive information from these temporary files.
Details
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.
Impact
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.
Workarounds
Ensure 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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2025-48382 can be triaged on real exposure rather than presence alone.
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.
