The Forminator WordPress plugin before 1.24.1 does not use an atomic operation to check whether a user has already voted, and then update that information. This leads to a Race Condition that may allow a single user to vote multiple times on a poll.
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
