With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. From version 0.2.5 to before version 0.2.10, an unauthenticated remote code execution (RCE) vulnerability exists in the MCP stdio configuration validation. The application allows unrestricted user registration, meaning any attacker can create an account and exploit the command injection flaw. Despite implementing a whitelist for allowed commands (npx, uvx) and blacklists for dangerous arguments and environment variables, the validation can be bypassed using the -p flag with npx node. This allows any attacker to execute arbitrary commands with the application's privileges, leading to complete system compromise. This issue has been patched in version 0.2.10.
