The str_rot_pass function in vendor/atholn1600/php-proxy/src/helpers.php in PHP-Proxy 5.1.0 uses weak cryptography, which makes it easier for attackers to calculate the authorization data needed for local file inclusion.

Exploit prediction

1.13% chance of exploitation in the next 30 days, higher than 66% of all scored CVEs (FIRST EPSS, 2026-11-08).
