CVE-2026-91750: Server-Side Request Forgery (SSRF) in Tencent WeKnora
WeKnora before 0.7.0 fails to re-validate HTTP redirect targets in the POST /api/v1/knowledge-bases/:id/knowledge/url endpoint when downloading documents from user-supplied URLs. Authenticated attackers can bypass initial SSRF validation by supplying a public URL that redirects to internal network addresses, allowing access to internal services and cloud metadata.
AI Analysis
Technical Summary
Tencent WeKnora before version 0.7.0 contains an SSRF vulnerability in the POST /api/v1/knowledge-bases/:id/knowledge/url endpoint.
