Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Remote Code Execution: Direct evaluation of arbitrary PHP code from standard input allowed remote execution when the vendor folder was exposed to HTTP requests. This was mitigated by restricting execution to PHP CLI/phpdbg environments and eventually removing the helper script entirely.

Insecure Deserialization: Isolated test runs writing results to temporary storage allowed local write-after-exit race conditions or untrusted coverage file parsing to trigger deserialization. Fixes introduced cryptographic validation using random nonces and hash_equals before deserialization.

Argument Injection: Forwarding unneutralized PHP INI directives containing newline or carriage return characters to child processes allowed attackers to inject arbitrary INI settings, leading to command execution.
