What is CVE-2026-107447?

The Contest Gallery WordPress plugin prior to version 34.0.1 suffers from an improper authentication vulnerability that fails to adequately verify user identities for voting. By trusting client-supplied request headers and an unbounded client-generated token, the plugin allows unauthenticated users to cast multiple votes in contests, compromising the integrity of the voting process. This flaw can lead to inflated vote counts for contest entries, affecting fair competition.

Affected Version(s)

Contest Gallery 0 < 34.0.1

Exploit Proof of Concept (PoC)
