s2Member <= 260127 - Unauthenticated Privilege Escalation via Account Takeover_CVE-2026-1994

{
    "lastseen": "",
    "description": "The s2Member plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 260127. This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account.",
