CVE-2026-58473

Cognee < 1.2.0 Unauthorized LLM Configuration Overwrite via /api/v1/settings

Published Jul 7, 2026 CVSS 4.0 · 9.3 Critical EPSS < 1% KEV · Not listed
Description
Cognee before 1.2.0 contains an improper access control vulnerability that allows unauthenticated attackers to overwrite the global LLM provider configuration by self-registering an account and calling the settings endpoint, which performs no admin or superuser check. Attackers can redirect all LLM operations instance-wide to an attacker-controlled endpoint by exploiting the process-wide singleton configuration cache, enabling exfiltration of prompts, uploaded documents, extracted entities, and knowledge graph content from all users.
