CVE-2026-12472: CWE-862 Missing Authorization in themeum Kirki – Freeform Page Builder, Website Builder & Customizer
The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.0.11. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to send arbitrary HTML-injected emails — including phishing messages embedding a real, valid WordPress password-reset URL for the targeted user — to any registered user via the site's own mail server, abusing its SPF/DKIM reputation. The attacker-controlled emailSubject parameter is passed to wp_mail() with only sanitize_text_field() applied, while emailBody 'text' items are concatenated raw into the HTML email body with no escaping, and 'chip' items can include the genuine WordPress password-reset link for the targeted account.
AI Analysis
Technical Summary
CVE-2026-12472 is an authorization bypass vulnerability (CWE-862) in the Kirki – Freeform Page Builder, Website Builder & Customizer WordPress plugin. The plugin fails to properly verify user authorization before allowing actions that send emails. Attackers can exploit this to send arbitrary HTML-injected emails to registered users, abusing the site's mail server reputation. The emailSubject parameter is sanitized only with sanitize_text_field(), while emailBody text items are concatenated without escaping, and 'chip' items can embed genuine WordPress password-reset URLs for targeted users. This vulnerability affects all versions up to and including 6.0.11.
Potential Impact
An unauthenticated attacker can send phishing emails that appear to originate from the legitimate site, including valid password-reset links for targeted users. This can lead to phishing attacks leveraging the site's trusted mail server reputation (SPF/DKIM), potentially compromising user accounts. There is no direct confidentiality or availability impact reported, but the integrity of user trust and account security is at risk.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the plugin's email-sending functionality and monitor for suspicious email activity. Avoid exposing the plugin's features to unauthenticated users. Follow vendor updates closely for an official fix.
