AnalysisAIv1 – Mar 12, 2026

WeKnora's document import feature is vulnerable to Server-Side Request Forgery through HTTP redirects, allowing unauthenticated remote attackers to bypass URL validation controls and access internal services despite backend protections against private IPs and metadata endpoints. The vulnerability affects WeKnora versions prior to 0.2.12 when deployed in Docker environments, where host.docker.internal addresses are not blocked. Public exploit code exists and no patch is currently available.

Classified as CWE-918 (Server-Side Request Forgery (SSRF)). Affects Weknora. WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior to version 0.2.12, the application's "Import document via URL" feature is vulnerable to Server-Side Request Forgery (SSRF) through HTTP redirects. While the backend implements comprehensive URL validation (blocking private IPs, loopback addresses, reserved hostnames, and cloud metadata endpoints), it fails to validate redirect targets. An attacker can bypass all protections by using a redir

DescriptionGitHub Advisory

WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior to version 0.2.12, the application's "Import document via URL" feature is vulnerable to Server-Side Request Forgery (SSRF) through HTTP redirects. While the backend implements comprehensive URL validation (blocking private IPs, loopback addresses, reserved hostnames, and cloud metadata endpoints), it fails to validate redirect targets. An attacker can bypass all protections by using a redirect chain, forcing the server to access internal services. Additionally, Docker-specific internal addresses like host.docker.internal are not blocked. This issue has been patched in version 0.2.12.

Executive ViewAI

Why It Matters

Organizations using WeKnora should be aware of moderate risk from CVE-2026-30247, a server-side request forgery vulnerability rated CVSS 5.9. Users could be tricked into performing unintended actions. Proof-of-concept code is publicly available. Organizations should apply vendor updates when available and monitor for exploitation.

Business Impact: Low
Compensating Controls

Apply vendor patch. If patching is delayed: implement egress filtering, block metadata endpoints.
