GHSA-6x6h-qqr7-855w: lightrag-hku (CVE-2026-61736)

Package	Ecosystem	Affected	Fixed in
lightrag-hku	PyPI	<1.5.4	1.5.4

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

LightRAG versions before 1.5.4 default to a CORS setting of wildcard origins combined with credentials allowed, so the server echoes any requesting origin for credentialed cross-origin requests. A malicious website visited by a logged-in LightRAG user can make authenticated API calls, potentially reading documents and knowledge graph data or deleting the document store. Upgrade to lightrag-hku 1.5.4 or later.

Written 5 Nov 2026.
