## Affected packages

- `code.gitea.io/gitea` (Go): affected `<1.27.0`; fixed in `1.27.0`

## Machine-written summary

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

> Gitea versions before 1.27.0 are affected. An attacker who gets an administrator to run restore-repo on a malicious dump can make the server run git fetch against an attacker-chosen URL, enabling SSRF and reading local git repositories. Upgrade to Gitea 1.27.0; until then, do not restore untrusted dumps.

Written 6 Nov 2026.

## 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-xmj7-xj85-hfc3>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
