CVE-2026-54549 (GCVE-0-2026-54549)

Vulnerability from nvd – Published: 2026-09-15 17:18 – Updated: 2026-09-16 14:44

Title

Meta Ads MCP: Server-Side Request Forgery (SSRF) in `upload_ad_image` via Unrestricted `image_url` Fetch

Summary

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.

Title

Meta Ads MCP: X-Pipeboard-Token Header Auth Bypass Reuses Operator Meta Token

Summary

Meta Ads MCP is a Model Context Protocol (MCP) server that lets AI assistants run Meta Ads. Prior to version 1.0.115, AuthInjectionMiddleware in meta_ads_mcp/core/http_auth_integration.py rejects HTTP MCP requests only when both auth_token and pipeboard_token are absent, while extract_token_from_headers() does not recognize X-Pipeboard-Token as a primary credential. A network caller using the streamable-http transport can therefore send any X-Pipeboard-Token value, pass the guard without establishing authentication context, and cause get_auth_token() to fall back to the server operator's META_ACCESS_TOKEN. Subsequent MCP tools execute with the operator's Meta credentials and can read or modify the operator's Meta Ads data. Deployments using the default stdio transport or without META_ACCESS_TOKEN are not affected. This issue is fixed in version 1.0.115.

Title

Meta Ads MCP: Unauthenticated HTTP MCP Tool Execution Leaks Operator Meta Access Token

Summary

Meta Ads MCP is a Model Context Protocol (MCP) server that lets AI assistants run Meta Ads. Prior to version 1.0.109, `AuthInjectionMiddleware.dispatch()` at `http_auth_integration.py:272` unconditionally forwards unauthenticated Streamable HTTP requests to downstream MCP tool handlers without issuing a `401` response, allowing any network-reachable caller to invoke MCP tools without authentication. When no per-request credential is present, tool handlers fall back to the `META_ACCESS_TOKEN` environment variable, and when the downstream Meta Graph API call fails, `api.py:263–269` serialises the raw `httpx` request URL—including the operator's `access_token` as a query parameter—into the JSON-RPC response body, delivering the credential to the unauthenticated caller. Version 1.0.109 fixes the issue.

CVE-2026-54549 (GCVE-0-2026-54549)

Title

Meta Ads MCP: Server-Side Request Forgery (SSRF) in `upload_ad_image` via Unrestricted `image_url` Fetch

Summary

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.

Title

Meta Ads MCP: X-Pipeboard-Token Header Auth Bypass Reuses Operator Meta Token

Summary

Meta Ads MCP is a Model Context Protocol (MCP) server that lets AI assistants run Meta Ads. Prior to version 1.0.115, AuthInjectionMiddleware in meta_ads_mcp/core/http_auth_integration.py rejects HTTP MCP requests only when both auth_token and pipeboard_token are absent, while extract_token_from_headers() does not recognize X-Pipeboard-Token as a primary credential. A network caller using the streamable-http transport can therefore send any X-Pipeboard-Token value, pass the guard without establishing authentication context, and cause get_auth_token() to fall back to the server operator's META_ACCESS_TOKEN. Subsequent MCP tools execute with the operator's Meta credentials and can read or modify the operator's Meta Ads data. Deployments using the default stdio transport or without META_ACCESS_TOKEN are not affected. This issue is fixed in version 1.0.115.

Severity

CVE-2026-48039 (GCVE-0-2026-48039)

Vulnerability from cvelistv5 – Published: 2026-08-07 19:29 – Updated: 2026-08-07 19:42

Title

Meta Ads MCP: Unauthenticated HTTP MCP Tool Execution Leaks Operator Meta Access Token

Summary

Meta Ads MCP is a Model Context Protocol (MCP) server that lets AI assistants run Meta Ads. Prior to version 1.0.109, `AuthInjectionMiddleware.dispatch()` at `http_auth_integration.py:272` unconditionally forwards unauthenticated Streamable HTTP requests to downstream MCP tool handlers without issuing a `401` response, allowing any network-reachable caller to invoke MCP tools without authentication. When no per-request credential is present, tool handlers fall back to the `META_ACCESS_TOKEN` environment variable, and when the downstream Meta Graph API call fails, `api.py:263–269` serialises the raw `httpx` request URL—including the operator's `access_token` as a query parameter—into the JSON-RPC response body, delivering the credential to the unauthenticated caller. Version 1.0.109 fixes the issue.
