CVE-2026-49948 – Mem0 0.2.8 Missing Authorization via POST /configure Endpoint

CVE ID :CVE-2026-49948

Published : June 9, 2026, 4:16 p.m. | 19 minutes ago

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.

Severity: 8.6 | HIGH
