Held back: archives of this plugin that did not pass the automatic checks and are not published. Findings reviewed: matches of the rules that were checked and resolved before publication.

How every version is checked

Malware scan ClamAV

Every file of every version against the ClamAV signature database.

Pattern rules YARA

Web shells, obfuscated loaders, encoded PHP and known nulling patterns (php-malware-finder plus MeteorGPL rules).

PHP analysis Heuristics

Token-level analysis: remote includes, request input reaching shell functions, decoders feeding eval, PHP hidden in images, fonts or archives, server handler overrides.

License integrity De-null signatures

License, activation and update code is compared with the vendor’s own code and the previous version; altered license code is never published.

PHP syntax PHP lint

Every PHP file parses on the PHP version the repository supports.

Woocommerce Custom Product Addons Pro <= 5.4.1 - Unauthenticated Remote Code Execution via Custom Pricing Formula

  • Affected versions: ≤ 5.4.1
  • Fixed in: 5.4.2
  • CVE: CVE-2026-4001
  • Published:

The vendor fixed it in 5.4.2; that version is not in the repository yet.

No version in this repository is affected.

Details

The Woocommerce Custom Product Addons Pro plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 5.4.1 via the custom pricing formula eval() in the process_custom_formula() function within includes/process/price.php. This is due to insufficient sanitization and validation of user-submitted field values before passing them to PHP's eval() function. The sanitize_values() method strips HTML tags but does not escape single quotes or prevent PHP code injection. This makes it possible for unauthenticated attackers to execute arbitrary code on the server by submitting a crafted value to a WCPA text field configured with custom pricing formula (pricingType: "custom" with {this.value}).

Remediation: Update to version 5.4.2, or a newer patched version

CWE-95: Improper Neutralization of Directives in Dynamically Evaluated Code
