Summary
llama-index-core Command Injection vulnerability
Details

A command injection vulnerability exists in the run-llama/llamaindex repository, specifically within the safeeval function. Attackers can bypass the intended security mechanism, which checks for the presence of underscores in code generated by LLM, to execute arbitrary code. This is achieved by crafting input that does not contain an underscore but still results in the execution of OS commands. The vulnerability allows for remote code execution (RCE) on the server hosting the application.
