A path traversal vulnerability allowing arbitrary file read has been identified in the ErlichLiu Claude-Agent-SDK, specifically in the 04-agent-teams component, up to commit b185aa7ff0d864581257008077b4010fca1747bf. The vulnerability arises in the app/api/agent-output/route.ts file, where the outputFile parameter is manipulated, leading to unauthorized access to local files. This issue can be exploited remotely, potentially allowing attackers to read sensitive files such as configuration data, credentials, or source code.
It is recommended to restrict the outputFile parameter to a server-controlled directory, implement authentication and authorization checks on the API endpoint, and avoid returning raw file contents unless explicitly authorized by the server.
