CVE-2026-30857
MEDIUMWeKnora < 0.3.0 - Authenticated Cross-Tenant Authorization Bypass via Knowledge Base Copy Endpoint
Title source: llmDescription
WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior to version 0.3.0, a cross-tenant authorization bypass in the knowledge base copy endpoint allows any authenticated user to clone (duplicate) another tenant’s knowledge base into their own tenant by knowing/guessing the source knowledge base ID. This enables bulk data exfiltration (document/FAQ content) across tenants. This issue has been patched in version 0.3.0.
