## Critical

Critical, because:

- CVSS score 10.0: 9.0 or more.

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

## Affected packages

- `pheditor/pheditor` (Packagist): affected `<2.0.8`; fixed in `2.0.8`

## Machine-written summary

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

> Pheditor versions before 2.0.8 are affected. On instances where the default password has not been changed, the forced password-change flow does not check the submitted password against the current one, so an unauthenticated remote attacker can set a new admin password and obtain an authenticated session. Upgrade to Pheditor 2.0.8. The source lists 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-f25v-x6vr-962g>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
