CVE-2026-12721

The Kirki plugin version 6.0.11 and earlier contains an unauthenticated Insecure Direct Object References (IDOR) vulnerability. This allows an attacker to access protected resources or data without authentication.

The Kirki WordPress plugin before version 6.0.12 does not validate a user-supplied URL before requesting it server-side, allowing unauthenticated attackers to make the site issue HTTP requests to arbitrary hosts (Server-Side Request Forgery).

The Kirki plugin for WordPress contains a Blind SQL Injection vulnerability in versions up to and including 6.0.12. The issue is due to improper neutralization of special elements used in SQL commands.

The Kirki WordPress plugin contains a deserialization of untrusted data vulnerability allowing object injection. This affects versions up to and including 6.0.12.

The Kirki WordPress plugin before version 6.0.14 does not perform a capability check on some endpoints of one of its public AJAX actions, allowing unauthenticated users to retrieve the email addresses of registered users and comment authors, as well as non-public page content and settings.

The Kirki WordPress plugin before 6.2.3 does not properly validate files in archives uploaded by users with the Editor role and does not remove all unwanted files after extraction, allowing such users to upload arbitrary files to a web accessible directory, leading to Stored XSS and RCE on some server configurations.

Unauthenticated XSS vulnerability in Kirki versions up to 6.2.3. An attacker can inject malicious scripts that execute in the victim's browser.

The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress up to version 6.1.1 is vulnerable to authorization bypass, allowing authenticated attackers with custom-level access to read arbitrary user metadata and sensitive user record fields, including email address, roles, registration date, and user_meta values, belonging to any user including administrators.

The Kirki plugin for WordPress up to version 6.1.1 is vulnerable to Directory Traversal via the 'data' parameter. Authenticated attackers with editor-level access and above can read arbitrary files on the server, including sensitive information, by bypassing the strpos()-based guard with traversal sequences in the URL.

The Kirki WordPress plugin before 6.2.1 does not properly authorise its front-end form submission REST routes and passes attacker-controlled input through shortcode execution, allowing unauthenticated users to run any shortcode registered on the site, which on a default install leads to disclosure of the site administrator's email address and an arbitrary-recipient mail relay from the victim's domain.
