Technical summary

The wpForo Forum WordPress plugin, versions 3.0.0 to 3.1.5, does not verify client-supplied IP address headers before using them to key its per-visitor rate limit on paid AI requests. This allows unauthenticated attackers to bypass rate limiting on paid AI requests by spoofing the IP address header, potentially leading to the exhaustion of site owner's metered AI credits. Site owners should verify plugin versions and update to 3.1.6 or later to mitigate this vulnerability. The vulnerability has a medium severity with a CVSS score of 5.3.
