CVE-2022-46020Public exploitNetwork attack vector

Unauthenticated code execution via file-type modification

Published Dec 20, 2022 · Updated Apr 17, 2025

Unrestricted file upload in WBCE CMS 1.5.4 allows remote attackers to execute server-side code by changing an upload file type. The public record does not identify the upload handler or disclose how its file-type validation accepts a dangerous server-executable file. No authentication is required according to the published CVSS assessment, and successful exploitation executes code in the web server context.
