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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-54549)\n\nAffected packages:\n\n- `meta-ads-mcp < 1.0.115`\n\nPatched in:\n\n- `meta-ads-mcp 1.0.115`\n\nSource: https://github.com/advisories/GHSA-45gf-fjxp-cjpq","depth":"midnight","depthScore":58,"depthScoreParts":{"impact":45.7,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":204971,"id":"CVE-2026-54549","ts":1789570699540,"field":"exploit_available","old":"false","new":"true"}]}
