CVE-2026-30247Public exploitNetwork attack vector

Internal data disclosure via unchecked redirect targets

Published Mar 7, 2026 · Updated Mar 7, 2026

SSRF in Tencent WeKnora before 0.2.12 allows remote authenticated users to read internal service responses through crafted URL imports. The URL-import endpoint checks only the initial URL, then follows 307 responses without applying IsSSRFSafeURL to each redirect target. A valid token and an attacker-controlled redirect are required; successful requests expose responses from services reachable by the backend.
