## Affected packages

- `github.com/rclone/rclone` (Go): affected `<1.75.1`; fixed in `1.75.1`

## Machine-written summary

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

> GHSA-p6m2-r3w9-mpxw affects the Go module github.com/rclone/rclone before 1.75.1. When rclone's local backend runs with symlink support enabled (--links or links=true), a remote client sending a crafted HTTP Range request for a symlink object can make the request handler panic. An unauthenticated attacker needs only network access to a served symlink, and the panic fails that single request. Upgrade to 1.75.1 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-p6m2-r3w9-mpxw>, or `POST https://api.agentprime.io/v1/match` with your packages (<https://agentprime.io/api.md>)
