Cross-site request forgery (CSRF) in Landing Page Builder (1.5.3.6 and older)

Affected: 1.5.3.6 and older
Fixed in: 1.5.3.7 *
Access needed (per CVSS): No login needed; someone on the site has to click a link or open a page
Range from: CVE record (the advisory publisher) · score by Wordfence

Details from the advisory

The Landing Page Builder – Coming Soon page, Maintenance Mode, Lead Page, WordPress Landing Pages plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.5.3.6. This is due to missing or incorrect nonce validation on the ulpb_admin_ajax function. This makes it possible for unauthenticated attackers to create, update, retitle, or change the post status, slug, and type of arbitrary posts and write ULPB_DATA post meta via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This attack requires the victim to hold an editor-level or administrator session, as the wp_ajax_ulpb_admin_data action enforces a capability check that the forged request must satisfy by inheriting the logged-in user's session cookies.
