Deeper analysis

The JetEngine WordPress plugin before version 3.1.3.1 is affected by an unrestricted file upload vulnerability tracked as CVE-2023-1406. The flaw, classified under CWE-434, allows uploaded files to be stored without sufficient checks to prevent them from being executable, which can result in remote code execution on the server. The issue carries a CVSS 3.1 score of 8.8, reflecting network attack vector, low complexity, and low privileges required.

An authenticated attacker with the ability to upload files through the plugin can supply executable content that the server will subsequently run, achieving arbitrary code execution with impacts to confidentiality, integrity, and availability. This scenario requires no user interaction and can be performed over the network by any user granted upload permissions by the plugin.

Public references from WPScan document the vulnerability and point to the availability of a fixed release in JetEngine 3.1.3.1 or later as the primary remediation path.

EPSS for the CVE reached a peak of 0.1012 on 2026-04-24 before receding to the current value of 0.0793, indicating a period of elevated exploitation interest after disclosure.
