Description

WordPress Plugin Jetpack by WordPress.com is prone to multiple vulnerabilities, including cross-site scripting and security bypass 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, allowing the attacker to steal cookie-based authentication credentials and launch other attacks, or to perform otherwise restricted actions and subsequently change Post By Email settings or access Feedback posts. WordPress Plugin Jetpack by WordPress.com version 4.0.3 is vulnerable; prior versions may also be affected.

Remediation

Update to plugin version 4.0.4 or latest
