CVE-2026-4808Network attack vector

Administrator-level file upload via missing type validation

Published Apr 8, 2026 · Updated Apr 8, 2026

Arbitrary file upload in Gerador de Certificados – DevApps 1.3.6 and earlier allows remote authenticated users to write files to the server. The moveUploadedFile() function moves uploaded content into server storage without first validating whether its file type is permitted. Administrator-level WordPress access is required; code execution depends on the server treating the uploaded file as executable content.
