CVE-2026-8907 rahulbhangale CVE debrief

CVE-2026-8907 is a Cross-Site Request Forgery (CSRF) vulnerability in the WP-Ultimate-Map plugin for WordPress, affecting versions up to and including 1.1. The vulnerability is caused by missing nonce validation on the process_init() function, which saves plugin settings via update_option(). This allows unauthenticated attackers to change plugin settings and inject arbitrary web scripts by tricking a site administrator into performing an action such as clicking on a link.

Who should care

Users of the WP-Ultimate-Map plugin for WordPress, particularly those with versions up to and including 1.1, should be aware of this vulnerability and take necessary actions to protect their sites.

Technical summary

The WP-Ultimate-Map plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.1. This is due to missing nonce validation on the process_init() function hooked to admin_init, which saves plugin settings (zoom-level, focus-lat, focus-lng, sel_places, sel_routes) via update_option() based solely on the presence of a save-setting POST parameter. Additionally, the saved values — particularly zoom-level — are stored without sanitization and later echoed into an HTML attribute (and inline JavaScript) on the settings page without escaping.

Defensive priority

MEDIUM

Recommended defensive actions

  • Update the WP-Ultimate-Map plugin to a version beyond 1.1.
  • Implement proper nonce validation for the process_init() function.
  • Sanitize and escape saved values, particularly zoom-level, before echoing them into HTML attributes or inline JavaScript.

Evidence notes

The CVE-2026-8907 vulnerability has a CVSS score of 6.1 and is classified as MEDIUM severity. The vulnerability allows for Cross-Site Request Forgery, enabling unauthenticated attackers to change plugin settings and inject arbitrary web scripts.
