CVE-2026-30857: Tencent Weknora

Medium severity, CVSS 5.3. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Tencent Weknora: before 0.3.0 (fixed in 0.3.0)
