Description
WeKnora is an LLM-powered framework designed for deep document understanding and semantic retrieval. Prior to version 0.2.5, there is a command injection vulnerability that allows authenticated users to inject stdio_config.command/args into MCP stdio settings, causing the server to execute subprocesses using these injected values. This issue has been patched in version 0.2.5.
A command injection vulnerability has been identified in Tencent WeKnora versions prior to 0.2.5. This vulnerability allows authenticated users to inject commands and arguments into the MCP stdio settings, which the server then executes as subprocesses.
