Authenticated internal resource access via unvalidated assetPath
Published Jun 1, 2026 · Updated Jun 1, 2026
Server-side request forgery in AEM MCP Server allows remote authenticated users to make the server contact attacker-selected hosts. The getAssetMetadata handler appends .json to the caller-controlled assetPath and passes it to Axios without restricting it to approved AEM content roots, allowing absolute or protocol-relative input to redirect the outbound GET. Reachability requires access to the authenticated MCP or HTTP/JSON-RPC method, server egress to the chosen destination, and no upstream assetPath validation; the bounded consequence is access to network resources reachable from the server.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
