## Critical

Critical, because:

- CVSS score 9.6: 9.0 or more.

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

## Affected packages

- `praisonai-platform` (PyPI): affected `<0.1.4`; fixed in `0.1.4`

## Machine-written summary

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

> Any workspace member of praisonai-platform before 0.1.4 can change their own role or another member's role, including promoting themselves to owner, through a PATCH request to the members endpoint. The source says the endpoint checks only for membership, not for owner or admin rights, and does not stop a caller from assigning a role above their own. An attacker with an ordinary member account in a workspace could take over that workspace, including demoting the real owner. Upgrade to praisonai-platform 0.1.4, which is listed as the fixed version. The source gives no other workaround.

## 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-c2m8-4gcg-v22g>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
