## Description

iTerm2 before 3.7.7beta2 has an argument injection vulnerability in the x-man-page: URL handler, allowing an attacker to execute arbitrary commands with the privileges of the logged-in user by inducing the user to open a crafted URL in iTerm2. Percent-encoded NUL characters survive input sanitization and are subsequently converted to whitespace during command-line parsing, allowing injection of additional arguments to /usr/bin/man. An attacker can inject the -P option to select an attacker-controlled pager command. NOTE: this issue exists because of an incomplete fix for CVE-2023-46321.
