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.

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 GHSA-g88v-2j67-9rmx is resolved across your whole dependency graph.
Workarounds
Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.
