## Critical

Critical, because:

- CVSS score 9.8: 9.0 or more.
- CVSS score 9.8 (7.0 or more) and EPSS 0.96 (0.1 or more): a high score and a real chance of exploitation in the next 30 days.

How we decide what’s critical: <https://agentprime.io/advisories/critical.md>

## Affected packages

- `pyload-ng` (PyPI): affected `<0.5.0b3.dev31`; fixed in `0.5.0b3.dev31`

## Machine-written summary

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

> pyload-ng versions before 0.5.0b3.dev31 are vulnerable to code injection. The source gives few details about how the flaw is triggered or what access an attacker needs. Upgrade pyload-ng to 0.5.0b3.dev31 or later.

## 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-pf38-5p22-x6h6>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
