Official description
The FooEvents for WooCommerce plugin for WordPress is vulnerable to unauthorized arbitrary file uploads due to an improper capability setting on the 'display_ticket_themes_page' function in versions up to, and including, 1.19.20. This makes it possible for authenticated attackers with contributor-level capabilities or above, to upload arbitrary files on the affected site's server which may make remote code execution possible. This was partially patched in 1.19.20, and fully patched in 1.19.21.

The underlying weakness: Improper Authorization
The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action.
How developers prevent this class of flaw
- Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries. Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
- Ensure that you perform access control checks related to your business logic. These checks may be different than the access control checks that you apply to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor.
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, consider using authorization frameworks such as the JAAS Authorization Framework and the OWASP ESAPI Access Control feature.
