WP Activity Log 5.3.2 was found to be vulnerable. Unvalidated user input is used directly in an unserialize function in myapp/classes/Writers/class-csv-writer.php.

Weakness

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

Affected Software

Name Vendor Start Version End Version
Wp_activity_log Melapress 5.3.2 (including) 5.3.2 (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.
