CVE-2026-107447
Contest Gallery < 34.0.1 - Unauthenticated Vote Restriction Bypass via Spoofable Client-IP and Forgeable Voter Identity
The Contest Gallery WordPress plugin before 34.0.1 does not reliably validate the visitor identity used to enforce its one-vote-per-entry restriction, trusting a client-supplied request header and an unbound client-generated token, which allows unauthenticated users to bypass the restriction and cast multiple votes for the same contest entry, inflating its vote total.
