Medium severity, CVSS 5.3. EPSS: 0.2% chance of exploitation in the next 30 days.

The wpForo Forum WordPress plugin from 3.0.0 before 3.1.6 does not verify the source of client-supplied IP address headers before using them to key its per-visitor rate limit on paid AI requests, allowing unauthenticated attackers to bypass the limit by spoofing the header and exhaust the site owner's metered AI credits.

Affected products

• Unknown Wpforo Forum: from 3.0.0, before 3.1.6 (fixed in 3.1.6)
