CVE-2022-40130Network attack vector

Poll-result manipulation via unsynchronized concurrent voting

Published Nov 18, 2022 · Updated Apr 28, 2026

Race condition in WP-Polls 2.76.0 and earlier allows remote authenticated users to alter poll results through concurrent votes. The vote_poll_process() function processes shared poll state without mutual exclusion, so overlapping vote requests can alter results inconsistently. Subscriber-level access is required, and the reported consequence is limited to poll-result integrity; no confidentiality or availability impact is published.
