AI Analysis
Technical Summary
CVE-2026-8422 is a Cross-Site Request Forgery vulnerability in the WordPress plugin 'Remove meta boxes per user role' (up to version 1.01). The issue arises from missing or incorrect nonce validation on the 'remove-meta-boxes-per-user-role' page, enabling unauthenticated attackers to craft requests that, if executed by an administrator, can alter the plugin's per-role meta box visibility settings. The vulnerability requires user interaction (UI:R) and has no privileges required (PR:N), with network attack vector (AV:N).
Potential Impact
An attacker can cause an administrator to unknowingly modify or reset meta box visibility settings for different user roles by tricking them into clicking a malicious link or performing a crafted action. This affects the integrity of plugin configuration but does not impact confidentiality or availability. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, administrators should avoid clicking on untrusted links or performing actions from unverified sources that could trigger changes in the plugin settings. Monitoring for updates from the plugin vendor is recommended.
