AI-suggested
A fix for this vulnerability exists and was introduced in commit ae7f406. Users should upgrade mem0 to a version later than 0.2.8 that includes this fix. Until upgraded, restrict API key distribution and monitor for unauthorized configuration changes. Patch status is not explicitly confirmed in the advisory, so verify the vendor's repository or advisory for the exact patched version and apply the official fix.
Description
Mem0 versions through 0.2.8, fixed in commit ae7f406, contain a missing authorization vulnerability in the self-hosted server component where the POST /configure endpoint modifies global LLM provider and embedder configuration but only verifies authentication via JWT or X-API-Key without validating the caller's role. Any authenticated user holding a distributed API key can redirect all LLM and embedder traffic to an attacker-controlled server, with the malicious configuration persisted to PostgreSQL and surviving server restarts to affect all users and API keys on the instance.
