Threats affecting pkg:golang/WeKnora

Tencent WeKnora versions from 0.2.11 up to but not including 0.8.2 contain a server-side request forgery (SSRF) vulnerability in the isRestrictedIP() function. This flaw misclassifies NAT64-prefixed IPv6 addresses as public, allowing authenticated attackers to supply URLs that resolve to internal network addresses or cloud metadata endpoints. The vulnerability is fixed in version 0.8.2.

A vulnerability has been found in Tencent WeKnora up to 0.3.6. Affected by this issue is the function getKnowledgeBaseForInitialization of the file internal/handler/initialization.go of the component Config API Endpoint. The manipulation of the argument kbId leads to authorization bypass. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
