CVE-2026-72576: Php File Upload Blacklist Validationcve-2026-72576-php-file-upload-blacklist-validation

File upload extension validation relies on a blacklist instead of an allowlist. Blacklists often fail to prevent uploading dangerous configuration files (such as .htaccess) or alternative executable extensions, leading to remote code execution.
