Description
FrankenPHP from 1.5.0 before 1.13.0 contains an incomplete environment sandbox vulnerability in which putenv writes to the process-wide OS environment via os.Setenv, leaking values across concurrent requests. Attackers reaching a request path that spawns child processes with the default environment through proc_open or exec can read secrets such as database passwords set by other requests.
