What to do
AI-suggested
Until a fix is released, restrict access to the mem0 openmemory/api component to trusted networks or users if possible, and monitor for any unusual activity related to memory access or service pauses.
Description
CVE-2026-59705 is a critical vulnerability in the mem0 openmemory/api component that allows unauthenticated attackers to read, write, and delete arbitrary user memories. Attackers can manipulate user_id parameters or access memory retrieval endpoints to expose private data. Additionally, they can invoke a global pause function that causes denial-of-service for all users. The vulnerability arises from a complete lack of authentication controls.
