Cognee vulnerabilities

A security flaw has been discovered in topoteretes cognee up to 1.5.4 in the get_user_id_by_email function of cognee/modules/users/authentication/get_api_auth_backend.py, part of the JWT Signing Key Handler component. Manipulation of the FASTAPI_USERS_JWT_SECRET argument results in hard-coded credentials. The attack can be launched remotely.

Cognee before version 1.2.0 contains an improper access control vulnerability that allows unauthenticated attackers to overwrite the global LLM provider configuration by self-registering an account and calling the settings endpoint, which performs no admin or superuser check. Attackers can redirect all LLM operations instance-wide to an attacker-controlled endpoint by exploiting the process-wide singleton configuration cache, enabling exfiltration of prompts, uploaded documents, extracted entities, and knowledge graph content from all users.

Cognee up to version 0.4.0 contains a critical remote code execution vulnerability in its notebook cell execution API endpoint. The endpoint executes arbitrary Python code provided by the user using the unsafe exec() function without any sandboxing, validation, or security controls.
