CVE-2026-58473: Topoteretes Cognee

Critical severity, CVSS 9.1. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Topoteretes Cognee: before 1.2.0 (fixed in 1.2.0)
