CVE-2026-80514 · Severity: medium · CVSS 5.3 · Published 2026-09-25

The wpForo Forum WordPress plugin fails to validate the source of IP address headers used to limit AI feature usage per visitor. An unauthenticated attacker can forge these headers to bypass per-IP rate limits on paid AI requests, allowing them to exhaust the site owner's metered AI credits without restriction.

## Technical details

The plugin uses client-supplied HTTP headers to key its per-visitor rate limiting for paid AI features without verifying the header source or legitimacy. An unauthenticated attacker can manipulate forwarded-for or similar headers to spoof different IP addresses and make unlimited AI requests that each appear to come from a different visitor, bypassing rate limits and exhausting metered credits. A fix is available in version 3.1.6.
