CVE-2026-104584
UnknownSummary
reNgine up to v2.2.0 and the current master branch (commit de4199222cca5618f1255930ce78987e47d43a99) is vulnerable to OS Command Injection via the custom_headers scan engine configuration field in web/reNgine/tasks.py (fetch_url and dir_file_fuzz functions).
Risk Assessment
An attacker can execute arbitrary OS commands on the server with the privileges of the reNgine process, potentially leading to full host compromise and data access. This is especially dangerous as reNgine is a security testing tool often run with elevated privileges.
Recommendation
Update reNgine to a patched version or apply a workaround by validating and sanitizing the custom_headers field. Restrict access to the reNgine interface and run it with minimal privileges.
