Description
A vulnerability was detected in inkeep agents 0.58.14. This vulnerability affects the function createDevContext of the file agents-api/src/middleware/runAuth.ts of the component runAuth Middleware. Performing a manipulation results in authentication bypass using alternate channel. The attack is possible to be carried out remotely. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
An authentication bypass vulnerability has been identified in Inkeep Agents version 0.58.14. This issue resides within the runAuth middleware, specifically in the createDevContext function. The vulnerability allows unauthenticated attackers to bypass authentication by injecting custom x-inkeep-* headers, enabling them to impersonate any tenant, project, or agent. This exploitation can lead to unauthorized data access, privilege escalation, and excessive consumption of backend API resources, particularly those linked to LLM providers like OpenAI or Anthropic.
Users are advised to avoid deploying Inkeep Agents in development or test modes on public-facing servers. If such a deployment is necessary, ensure that appropriate safeguards are in place to prevent unauthorized access.
