## Affected packages

- `azuracast/azuracast` (Packagist): affected `<0.23.6`; fixed in `0.23.6`

## Machine-written summary

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

> AzuraCast versions before 0.23.6 are vulnerable to password reset poisoning: the application trusts the client-supplied X-Forwarded-Host header, so an unauthenticated attacker can make the reset email link point to an attacker-controlled host. If a victim clicks that link, the attacker can capture the reset token and use it to change the password, which also removes two-factor authentication, leading to account takeover. Upgrade to version 0.23.6 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-gv7r-3mr9-h5x8>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
