CVE-2026-107447: Contest Gallery < 34.0.1 - Unauthenticated Vote Restriction Bypass via Spoofable Client-IP and Forgeable Voter Identity
- Severity: medium (CVSS 5.3 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.3% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-10-21 · updated 2026-10-21
- Weakness: CWE-290
Description
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.
Affected products
- Contest Gallery: before 34.0.1 — fixed in 34.0.1
How to fix
Upgrade to a fixed version: Contest Gallery 34.0.1. Check the vendor advisory for mitigations.
