CVE-2026-59705
mem0 - OpenMemory API Unauthenticated Access via Memory Endpoints
Description

mem0's openmemory/api component contains an unauthenticated access vulnerability that allows unauthenticated attackers to read, write, and delete arbitrary user memories by accessing API routers registered without authentication middleware. Attackers can supply arbitrary user_id parameters or directly access memory retrieval endpoints to expose private memory content, or invoke pause endpoints with global_pause=true to cause denial-of-service across all users.
