Description
WordPress Plugin Insert Pages is prone to multiple vulnerabilities, including cross-site scripting and security bypass vulnerabilities. Exploiting these issues may 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 perform otherwise restricted actions and subsequently access content and metadata from arbitrary posts/pages. WordPress Plugin Insert Pages version 3.6.1 is vulnerable; prior versions may also be affected.
Remediation
Update to plugin version 3.7.0 or latest
