Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for pipeboard-co/meta-ads-mcp, meta-ads-mcp.
  2. 2Review the reported fix. Update pipeboard-co/meta-ads-mcp to 1.0.115; meta-ads-mcp to 1.0.115 if you use the affected versions. Test the change in a non-production environment first.

Upstream source description

Meta Ads MCP is a Model Context Protocol (MCP) server that lets AI assistants run Meta Ads. Prior to version 1.0.115, the upload_ad_image tool in meta_ads_mcp/core/ads.py passes an attacker-controlled image_url to try_multiple_download_methods() in meta_ads_mcp/core/utils.py, where httpx.AsyncClient uses follow_redirects=True and performs HTTP requests without validating the scheme, host, or resolved IP address. In a streamable-http deployment, a network caller can use any non-empty authorization value because Meta credential validation occurs after the image download, then direct the server to loopback services, private-network addresses, cloud metadata endpoints, or redirect-chained internal targets. The resulting server-side request forgery can expose internal data, invoke state-changing internal services, or disrupt reachable services. This issue is fixed in version 1.0.115.
