Deeper analysis

The User Profile Builder WordPress plugin before version 3.11.8 is affected by CVE-2024-6366, a missing authorization vulnerability (CWE-434) that permits unauthenticated users to invoke the WordPress async upload handler. The flaw carries a CVSS 3.1 score of 9.1 and allows direct interaction with media upload functionality without any access controls.

Unauthenticated attackers reachable over the network can exploit the issue to upload arbitrary media files, resulting in high impact to confidentiality and integrity while availability remains unaffected.

The referenced WPScan advisory identifies the affected plugin versions and indicates that the issue is resolved in release 3.11.8. The associated EPSS score remains elevated near 0.92 with no material rise from a low baseline reported.
