Description
WordPress Plugin Jetpack-WP Security, Backup, Speed, & Growth is prone to multiple vulnerabilities, including cross-site scripting and information disclosure 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 or to obtain sensitive information which may help in launching further attacks. WordPress Plugin Jetpack-WP Security, Backup, Speed, & Growth version 3.7.0 is vulnerable; prior versions may also be affected.
Remediation
