The GDPR CCPA Compliance Support plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 2.3 via deserialization of untrusted input njt_gdpr_allow_permissions value. This allows unauthenticated attackers to inject a PHP Object.
Weakness
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
Affected Software
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Gpdr_ccpa_compliance_support | Ninjateam | * | 2.3 (including) |
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.
