CVE-2026-87959: CWE-284 Improper Access Control in WPBot
WPBot WordPress plugin versions from 8.7.2 up to but not including 8.7.6 contain an improper access control vulnerability. This flaw allows users with subscriber-level access to modify the plugin's Claude AI provider settings, including the API key used for outgoing AI requests. This occurs because the plugin does not perform a capability check on the AJAX action responsible for saving these settings.

Technical Summary
CVE-2026-87959 is an improper access control vulnerability (CWE-284) in the WPBot WordPress plugin before version 8.7.6.
