Description
WordPress Plugin W4 Post List 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, to steal cookie-based authentication credentials, or to obtain sensitive information which could aid in launching further attacks. WordPress Plugin W4 Post List version 2.4.5 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 2.4.6 or latest
