Psysh
Monthly
PsySH versions prior to 0.11.23 and 0.12.19 automatically execute a `.psysh.php` file from the current working directory during startup, allowing local attackers with write access to a directory to achieve arbitrary code execution when a user launches PsySH from that location. When a privileged user such as root or a CI runner executes PsySH in an attacker-controlled directory, this results in local privilege escalation. Public exploit code exists for this vulnerability and no patch is currently available.
