CVE-2025-0912

The Donations Widget plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 3.19.4 via deserialization of untrusted input from the Donation Form through the card_address parameter. This makes it possible for unauthenticated attackers to inject a PHP Object. The additional presence of a POP chain allows attackers to achieve remote code execution.

Weakness

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

Potential Mitigations

• Make fields transient to protect them from deserialization.
• An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
