CVE-2026-42076: Evolver: Command Injection via `execSync` in `_extractLLM()` function allows Remote Code Execution

April 22, 2026 (updated May 4, 2026)

A command injection vulnerability in the _extractLLM() function allows attackers to execute arbitrary shell commands on the server. The function constructs a curl command using string concatenation and passes it to execSync() without proper sanitization, enabling remote code execution when the corpus parameter contains shell metacharacters.
