DescriptionGitHub Advisory

WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior to version 0.3.2, an authorization bypass in tenant management endpoints of WeKnora application allows any authenticated user to read, modify, or delete any tenant by ID. Since account registration is open to the public, this vulnerability allows any unauthenticated attacker to register an account and subsequently exploit the system. This enables cross-tenant account takeover and destruction, making the impact critical. This issue has been patched in version 0.3.2.

AnalysisAI

Insufficient authorization checks in WeKnora's tenant management endpoints allow any authenticated user to read, modify, or delete arbitrary tenants, with public exploit code available. Since the application allows open registration, unauthenticated attackers can register an account and exploit this flaw to perform cross-tenant account takeover and data destruction. No patch is currently available for this high-severity vulnerability affecting WeKnora AI/ML framework versions prior to 0.3.2.
