CVE-2026-61808: Hkuds Lightrag

Critical severity, CVSS 9.8. EPSS: 2.5% chance of exploitation in the next 30 days.

LightRAG provides simple and fast retrieval-augmented generation. Through version 1.5.4, the LightRAG API server binds to all network interfaces with authentication disabled by default, allowing an unauthenticated network attacker to read indexed document content, upload or delete documents, modify the knowledge graph, cancel pipelines, clear caches, and consume LLM resources. This issue is mitigated in version 1.5.5rc1.

Affected products

• Hkuds Lightrag: before 1.5.5rc1 (fixed in 1.5.5rc1)
