CVE-2026-54547 (opens in a new tab)How to fix?
Upgrade meta-ads-mcp to version 1.0.115 or higher.
Overview
meta-ads-mcp is a Model Context Protocol (MCP) server for Meta Ads - Use Remote MCP at pipeboard.co for easiest setup
Affected versions of this package are vulnerable to Improper Authentication in the authentication process. An attacker can gain unauthorized access to sensitive Meta Ads data and perform actions as the server operator by sending an HTTP request with an arbitrary X-Pipeboard-Token header, which causes the system to fall back to the operator's Meta access token. This is only exploitable if the server is deployed in streamable-http mode with the META_ACCESS_TOKEN environment variable configured.
