## Affected packages

- `org.codelibs.fess:fess` (Maven): affected `<14.19.2`; fixed in `14.19.2`

## Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

> Fess versions before 14.19.2 create temporary files without explicitly restrictive permissions, in the createTempFile() method of SystemHelper. A local user on a shared system could read sensitive data in those files. Upgrade to Fess 14.19.2 or later. Until then, restrict local access to the host running Fess to trusted users only.

## Check whether this affects you

A Match means an installed version is in the affected range above. Most don’t affect the app; agentprime hasn’t analysed this one yet.

- With the agentprime MCP server (<https://api.agentprime.io/mcp>), ask your agent to check the project: `check_lockfile` sends a lockfile, `check_packages` a list of installed packages, and both return the Matches and the upgrades that clear them. `get_advisory` returns this record. Setup: <https://agentprime.io/mcp.md>
- In a browser: <https://agentprime.io/check/> reads your lockfile in the browser, never uploading it.
- Whether it touches your code, with file and line: the Claude Code plugin, <https://agentprime.io/plugin.md>
- As JSON: <https://api.agentprime.io/v1/advisories/GHSA-g88v-2j67-9rmx>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
