Summary

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.

Risk Assessment

Access to internal network resources and cloud metadata, potentially leading to leakage of sensitive information and further attacks.

Recommendation

Upgrade WeKnora to version 0.7.0 or later, which includes the fix for re-validating redirects.
