CVE-2026-50561 is a critical improper authentication vulnerability in Yuxi, a large-model-based intelligent knowledge base and knowledge graph agent development platform. Versions prior to 0.6.2 insufficiently validate the identity token supplied in the Authorization header and perform only a token validity check rather than adequately binding the token to the correct deployment instance and identity context. As a result, an administrator JWT generated in a different deployment instance or local testing environment can be accepted by another affected instance. This enables authentication bypass against backend management interfaces and can lead to unauthorized administrative access.
