CVE-2026-123024 Details
Description
A vulnerability has been found in agentscope-ai AgentScope up to 2.0.11. This impacts the function get_current_user_id of the file src/agentscope/app/deps.py of the component Agent Service. Such manipulation of the argument X-User-ID leads to missing authentication. The attack can be executed remotely. The exploit has been disclosed to the public and may be used. The pull request to fix this issue awaits acceptance.
A vulnerability exists in AgentScope versions through 2.0.11, where the Agent Service component lacks proper authentication. The issue arises because the service accepts the X-User-ID header as a valid identity without any verification. This flaw allows remote attackers to impersonate users and access or modify their data. The vulnerability has been publicly disclosed and is included in the CVE database.
Users are advised to implement server-side identity verification using JWT, API keys, or OAuth2. Until this is done, the service should be deployed behind an authenticated reverse proxy that validates and injects a verified X-User-ID, stripping untrusted headers. As a short-term measure, the service can be bound to 127.0.0.1 instead of 0.0.0.0.
