WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior to version 0.3.0, a DNS rebinding vulnerability in the web_fetch tool allows an unauthenticated attacker to bypass URL validation and access internal resources on the server, including private IP addresses (e.g., 127.0.0.1, 192.168.x.x). By crafting a malicious domain that resolves to a public IP during validation and subsequently resolves to a private IP during execution, an attacker can access sensitive local services and potentially exfiltrate data. This issue has been patched in version 0.3.0.
AnalysisAI
DNS rebinding in WeKnora's web_fetch tool allows authenticated attackers to bypass URL validation and access internal resources and private IP addresses on the server through malicious domains that resolve differently during validation versus execution. Public exploit code exists for this vulnerability, and versions prior to 0.3.0 are affected with no patch currently available. An attacker could leverage this to access sensitive local services and exfiltrate data from the affected system.
Technical ContextAI
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.
