CVE-2026-118376 Details
Description
WeKnora before 0.8.2 contains a server-side request forgery vulnerability in isRestrictedIP() that misclassifies NAT64-prefixed IPv6 addresses as public. Authenticated attackers can supply URLs resolving to NAT64 encodings of internal addresses via web_fetch or URL-based knowledge import to reach internal services or cloud metadata endpoints.
A server-side request forgery (SSRF) vulnerability has been identified in WeKnora versions prior to 0.8.2. The issue arises in the 'isRestrictedIP()' function, which incorrectly classifies NAT64-prefixed IPv6 addresses as public. This misclassification allows authenticated attackers to use URLs that resolve to NAT64 encodings of internal addresses, bypassing security measures to access internal services or cloud metadata endpoints.
Users can update to WeKnora version 0.8.3 or later, where this vulnerability has been fixed.
