CVE-2025-6688: Idokd Simple Payment

Critical severity, CVSS 9.8. EPSS: 0.5% chance of exploitation in the next 30 days.

The Simple Payment plugin for WordPress is vulnerable to Authentication Bypass in versions 1.3.6 to 2.3.8. This is due to the plugin not properly verifying a user's identity prior to logging them in through the create_user() function. This makes it possible for unauthenticated attackers to log in as administrative users.

Affected products

• Idokd Simple Payment: from 1.3.6, before 2.3.9 (fixed in 2.3.9)
