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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:L","score":8.3},"cwes":["CWE-918"],"references":["https://github.com/pipeboard-co/meta-ads-mcp/commit/7d9926336bbdac6285a988d043c4ccfe126c94c5","https://github.com/pipeboard-co/meta-ads-mcp/pull/138","https://github.com/pipeboard-co/meta-ads-mcp/releases/tag/1.0.115","https://github.com/pipeboard-co/meta-ads-mcp/security/advisories/GHSA-45gf-fjxp-cjpq","https://github.com/pipeboard-co/meta-ads-mcp/security/advisories/GHSA-45gf-fjxp-cjpq"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:54:41.405518556+00:00"},"epss":{"cve":"CVE-2026-54549","score":0.00399,"percentile":0.33858,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-45gf-fjxp-cjpq","url":"https://osv.dev/vulnerability/GHSA-45gf-fjxp-cjpq","summary":"meta-ads-mcp: Server-Side Request Forgery (SSRF) in `upload_ad_image` via Unrestricted `image_url` Fetch","modified":"2026-07-23T15:11:42.744080055Z","packages":[{"ecosystem":"PyPI","name":"meta-ads-mcp","purl":"pkg:pypi/meta-ads-mcp","ranges":["<1.0.115"],"fixed":["1.0.115"]}]},{"id":"PYSEC-2026-3485","url":"https://osv.dev/vulnerability/PYSEC-2026-3485","summary":"meta-ads-mcp: Server-Side Request Forgery (SSRF) in `upload_ad_image` via Unrestricted `image_url` Fetch","modified":"2026-07-23T15:00:15.304763138Z","packages":[{"ecosystem":"PyPI","name":"meta-ads-mcp","purl":"pkg:pypi/meta-ads-mcp","ranges":["<1.0.115"],"fixed":["1.0.115"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
