# CVE-2026-6294: Google PageRank Display \<= 1.4 - Cross-Site Request Forgery to Settings Update via Settings Page

- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-04-22 · Updated: 2026-04-22

## Affected

- byybora Google PageRank Display: through 1.4

## Description

The Google PageRank Display plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to and including 1.4. This is due to missing nonce validation in the gpdisplay_option() function, which handles the plugin settings page. The settings form does not include a wp_nonce_field(), and the form handler does not call check_admin_referer() or wp_verify_nonce() before processing the POST request. This makes it possible for unauthenticated attackers to trick a logged-in administrator into submitting a crafted request that changes the plugin's settings (stored via update_option()), such as the display style used to render the PageRank badge.
