CREATE TABLE / schema churnMITRE service request: 1988584
Status: RESERVED (pending a qualifying public reference per CNA Rules §5.3).
The mem0 1.0.0 server lacks authentication and authorization controls for its memory reset and table re-creation functionality accessible via the DELETE /memories endpoint. An unauthenticated attacker can send a DELETE request that triggers a reset operation, leading to the execution of a CREATE TABLE SQL statement. This can cause unexpected table re-creation, schema disruption, potential data loss, and denial of service for the memory management service.
Another unauthenticated branch of the reset workflow executes CREATE TABLE IF NOT EXISTS via PGVector.create_col() after destructive operations, letting remote callers force schema churn that breaks in-flight writers and can discard residual data depending on migration logic.
