CVE-2026-7158 — A vulnerability has been found in dmitryglhf mcp-url-downloader up to 4b8cf2de55f6e8864a77d108e8a94a5b8e4394c6

High CVSS 7.5

A vulnerability has been found in dmitryglhf mcp-url-downloader up to 4b8cf2de55f6e8864a77d108e8a94a5b8e4394c6. Affected by this issue is the function _validate_url_safe of the file src/mcp_url_downloader/server.py. Such manipulation of the argument url leads to server-side request forgery. The attack can be executed remotely. The exploit has been disclosed to the public and may be used. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. The project was informed of the problem early through an issue report but has not responded yet.

Matched remediation archetype

Server-side request forgery and unintended proxying

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Inventory server-side URL fetchers, webhooks, importers, previews, redirects, proxies, and protocol handlers reachable from untrusted input.
  • Map egress paths to internal services, metadata endpoints, loopback, private address space, and privileged control planes.
  • Review DNS resolution, redirect, proxy, credential-forwarding, and URL parsing behavior without requesting sensitive targets.

Remediate safely

  • Replace arbitrary destinations with named integrations or a strict allowlist of schemes, hosts, ports, and paths.
  • Resolve and validate every destination and redirect hop, then enforce egress policy independently of application checks.
  • Remove ambient credentials and sensitive headers from fetchers; apply response size, time, and content limits.
