WeKnora Authorization and Code Execution Flaws

SQL injection in WeKnora LLM document understanding framework allows authenticated users to extract arbitrary database contents. CVSS 9.9 with scope change. PoC available.

OS command injection in WeKnora from version 0.2.5 allows authenticated users to execute arbitrary system commands. CVSS 9.9 with scope change. PoC available.

Insufficient authorization checks in WeKnora's tenant management endpoints allow any authenticated user to read, modify, or delete arbitrary tenants, with public exploit code available. Since the application allows open registration, unauthenticated attackers can register an account and exploit this flaw to perform cross-tenant account takeover and data destruction. No patch is currently available for this high-severity vulnerability affecting WeKnora AI/ML framework versions prior to 0.3.2.

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.

Tool name collision in WeKnora's MCP client integration allows remote attackers with network access to register malicious tools that overwrite legitimate ones, enabling prompt injection attacks and potential data exfiltration. An attacker exploiting this vulnerability can redirect LLM execution to steal system prompts and context data, or execute arbitrary tools with the privileges of authenticated users. This affects WeKnora versions prior to 0.3.0.

WeKnora versions prior to 0.2.12 suffer from inadequate tenant isolation in database queries, permitting any authenticated user to access sensitive data from other tenants including API keys, model configurations, and private messages. The vulnerability affects multi-tenant deployments where account-level access controls fail to prevent cross-tenant data exfiltration. No patch is currently available for affected versions.

Weknora versions up to 0.3.0 is affected by authorization bypass through user-controlled key (CVSS 5.3).
