FKIE_CVE-2026-15212

Vulnerability from fkie_nvd - Published: 2026-07-23 20:17 - Updated: 2026-07-24 20:46
Severity
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Summary
The WPO365 | Login plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 43.2. This is due to the Ajax_Service::verify_ajax_request() helper gating its wp_verify_nonce() call behind the boolean option 'enable_nonce_check', which is absent from the default 'wpo365_options' array and therefore evaluates to false via get_global_boolean_var(); as a result, the wp_ajax_wpo365_update_settings handler (Ajax_Service::update_settings) accepts POSTs from cross-origin pages and forwards the attacker-supplied 'settings' payload (base64/JSON) to Options_Service::update_options(), which merges every key/value into wpo365_options without a key allowlist. This makes it possible for unauthenticated attackers to overwrite arbitrary plugin options — including enabling the SCIM REST endpoint (enable_scim), planting an attacker-known scim_secret_token, and setting new_usr_default_role to 'administrator' — via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
