CVE-2026-80514: CWE-348 Use of Less Trusted Source in wpForo Forum
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.
AI Analysis
Technical Summary
The wpForo Forum WordPress plugin from version 3.0.0 up to but not including 3.1.6 contains a CWE-348 vulnerability where it uses client-supplied IP address headers without verifying their source to enforce per-visitor rate limits on paid AI requests. An unauthenticated attacker can spoof these headers to bypass the rate limit, causing the site owner's AI credits to be exhausted.
Potential Impact
The vulnerability allows unauthenticated attackers to bypass rate limiting controls by spoofing IP address headers, which can lead to exhaustion of the site owner's metered AI credits. There is no direct impact on confidentiality or integrity, but availability is affected due to potential denial of service via resource exhaustion.
Mitigation Recommendations
No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, monitoring for unusual AI request patterns and restricting or validating client IP headers at a network or application firewall level may help mitigate exploitation.
