Description

A vulnerability was found in dh1011 auto-favicon up to f189116a9259950c2393f114dbcb94dde0ad864b. This issue affects the function generate_favicon_from_url of the file src/auto_favicon/server.py of the component MCP Tool. The manipulation of the argument image_url results in server-side request forgery. The attack may be performed from remote. The exploit has been made public and could be used. This product utilizes a rolling release system for continuous delivery, and as such, version information for affected or updated releases is not disclosed. The project was informed of the problem early through an issue report but has yet to receive a response.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for auto-favicon, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of auto-favicon for GHSA-vmh7-9c7h-2pgg. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Restrict outbound requests from the affected component to an allowlist of hosts, block access to link-local and internal address ranges at the network layer, and require authentication on internal services so a forged request cannot reach them unauthenticated.
