## Critical

Critical, because:

- CVSS score 9.8: 9.0 or more.

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

## Affected packages

- `astrbot` (PyPI): affected `<3.5.18`; fixed in `3.5.18`

## Machine-written summary

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

> AstrBot versions before 3.5.18 (PyPI package astrbot) use a hard-coded JWT signing key, which lets an attacker bypass dashboard authentication. An attacker who can reach the instance over the network can then install a malicious Python plugin and execute arbitrary commands on the host. Upgrade to astrbot 3.5.18 or later, which contains the fix.

## 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-4m32-cjv7-f425>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
