Description
WordPress Plugin Login by Auth0 is prone to multiple vulnerabilities, including cross-site scripting, CSV injection or cross-site request forgery vulnerabilities. Exploiting these issues could allow an attacker to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, to steal cookie-based authentication credentials, to execute arbitrary commands on the victim's system by the use of Microsoft Excel DDE function, to leak data via maliciously injected hyperlinks, or to perform certain administrative actions and gain unauthorized access to the affected application. WordPress Plugin Login by Auth0 version 3.11.3 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 4.0.0 or latest
