Image CAPTCHA for Contact Form 7 and WPForms through 3.3.29 contains a CAPTCHA bypass vulnerability that allows unauthenticated attackers to defeat the anti-automation control by exploiting a hardcoded static answer in the Contact Form 7 integration. Attackers can submit kc_captcha=kc_human to pass validation in cf7ic_check_if_spam() on every protected form, enabling automated contact-form spam and abuse of actions gated only by this CAPTCHA.

Explain CVE-2026-127206 for an engineer deciding whether to act. Use https://cve.bz/api/public/cves/CVE-2026-127206?via=ask-ai-copy and https://cve.bz/cve/CVE-2026-127206?via=ask-ai-copy as the source of truth: what is affected and which versions fix it, whether it is in CISA KEV, public exploits, and its EPSS (an internet-wide 30-day estimate of exploitation activity, not a forecast for my systems). If they give no fixed versions, use the CVE record https://cveawg.mitre.org/api/cve/CVE-2026-127206 or the vendor advisory, not third-party mirrors. Tell me how to check whether I am affected and how to verify a fix. Cite the sources and say where they are uncertain.
