Recurring patterns

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

Phar Deserialization: Attackers can supply a 'phar://' wrapper in output or input paths to trigger PHP object deserialization, potentially leading to remote code execution. This is tracked via CVE-2023-41330 and CVE-2023-28115.

Path Traversal: Insufficient cleanup checks allowed attackers to traverse out of designated temporary directories, enabling arbitrary file deletion during the temporary file cleanup phase.
