CVE-2026-14840: CWE-290 Authentication Bypass by Spoofing in YOP Poll
The YOP Poll WordPress plugin before 7.0.6 does not validate the connection's origin IP address and instead trusts client-controlled forwarding headers when enforcing its per-IP vote restriction, allowing unauthenticated attackers to bypass the vote limit and cast unlimited votes on a public poll.
