## Affected packages

- `com.powsybl:powsybl-commons` (Maven): affected `<6.7.2`; fixed in `6.7.2`

## Machine-written summary

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

> PowSyBl Core's powsybl-commons package (Maven com.powsybl:powsybl-commons) is vulnerable in versions before 6.7.2 to a polynomial ReDoS in the DataSource listNames(String regex) method. An attacker must control both the regular expression passed to that method and the names of files or resources being matched, which can cause heavy CPU use and slow the server for other users. Upgrade to powsybl-commons 6.7.2 or later. Applications that call listNames directly with user-supplied patterns should avoid passing untrusted regex input.

## 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-rqpx-f6rc-7hm5>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
