Description
WordPress Plugin Real3D FlipBook is prone to multiple vulnerabilities, including cross-site scripting, arbitrary file/directory deletion and arbitrary image upload vulnerabilities. An attacker may leverage these issues 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, to delete arbitrary files/directories, thus rendering the website unavailable, or to upload arbitrary images, which may facilitate unauthorized defacement of the website. WordPress Plugin Real3D FlipBook version 2.18.8 is vulnerable; prior versions may also be affected.
Remediation
Disable the plugin until a fix is available
