Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Path Traversal: Unsanitized cache keys containing directory traversal sequences (dots and slashes) or non-alphanumeric characters allow attackers to write or delete arbitrary files, leading to Local File Inclusion (LFI) or Remote Code Execution (RCE).
Insecure File Permissions: Creating cache directories and files without enforcing a strict umask configuration leaves cache contents world-writable (CVE-2015-5723), permitting local users to execute arbitrary code.
Race Condition: Non-atomic cache writing allows concurrent requests to read partially written or corrupted PHP cache files, potentially leading to denial of service or unexpected execution states.
