Critical severity: a successful attack would have severe impact.

What to do

  1. Check which version of Integration for Google Sheets and Contact Form 7, WPForms, Elementor, Ninja Forms you run against the affected versions below, and install the vendor's latest release.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

The Integration for Google Sheets and Contact Form 7, WPForms, Elementor, Ninja Forms plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.1.1 via deserialization of untrusted input within the verify_field_val() function. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain in the Contact Form 7 plugin, which is likely to be used alongside, allows attackers to delete arbitrary files, leading to a denial of service or remote code execution when the wp-config.php file is deleted.

The underlying weakness: Deserialization of Untrusted Data

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

How developers prevent this class of flaw

  • If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
  • When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
  • Explicitly define a final object() to prevent deserialization.
