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.
