## Machine-written summary

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

> Homer (github.com/sipcapture/homer-app), all versions before 0.0.0-20260625091610-b2e942031ff8, creates a default admin account with the hardcoded password "sipcapture" on fresh deployments that use internal authentication, and does not force a password change at first login. An attacker who can reach the login endpoint of such an instance can sign in as admin with full administrative access. Upgrade to 0.0.0-20260625091610-b2e942031ff8 or later, which contains the fix. Until upgrading, change the admin password on any existing deployment.

## 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-6xp5-7rcx-xfgx>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
