A race condition in the affected WordPress rating plugin through 3.3.4 allows remote authenticated users to alter post vote totals. Public advisories identify concurrent vote updates but do not disclose the affected function or the operation that lacks synchronization. Subscriber-level WordPress access is required, and successful requests only increase or decrease rating votes; no confidentiality or availability impact is reported.
