What is CVE-2026-30855?

The WeKnora framework, designed for advanced document understanding and semantic retrieval, exhibits an authorization bypass flaw in its tenant management endpoints prior to version 0.3.2. This vulnerability allows authenticated users to manipulate tenant information without proper restrictions, and as account registration is publicly accessible, it enables unauthorized individuals to register accounts. This loophole can be exploited to conduct cross-tenant account takeover and modification operations, including the deletion of tenant data. A fix has been implemented in version 0.3.2 to address this issue.

Affected Version(s)
