This makes it possible for unauthenticated attackers to recover the dummy user password directly from a single HTTP request and use it to authenticate as any of the 25 built-in dummy accounts (such as antawn, chynna, or kiki) through `wp-login.php`, potentially achieving privilege escalation if any dummy account holds an elevated role. Exploitation requires that an administrator has previously created dummy users via the plugin's Tools page."}],"title":"UsersWP <= 1.2.78 - Unauthenticated Account Access via Predictable Dummy User Password Disclosed through Registration Form Hash","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/7c458034-9c44-4b46-8845-4c05bea043a0?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.78/includes/class-tools.php#L606"},{"url":"https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.78/includes/class-templates.php#L850"},{"url":"https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.78/includes/class-forms.php#L5244"},{"url":"https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.78/includes/class-userswp.php#L565"},{"url":"https://github.com/AyeCode/userswp/archive/refs/heads/master.zip"},{"url":"https://plugins.trac.wordpress.org/changeset/3774438/userswp/trunk/includes/class-tools.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-287 Improper Authentication","cweId":"CWE-287","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","baseScore":6.5,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Kuba"}],"timeline":[{"time":"2026-10-29T17:10:44.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-30T17:58:07.000Z","lang":"en","value":"Disclosed"}]}}}
