CVE-2026-4808 is an arbitrary file upload vulnerability in the Gerador de Certificados – DevApps WordPress plugin (versions up to 1.3.6). The issue arises from the moveUploadedFile() function lacking proper validation of uploaded file types. Authenticated users with Administrator privileges can exploit this to upload malicious files, potentially leading to remote code execution on the web server. The vulnerability has a CVSS 3.1 score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), reflecting network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. There is no vendor advisory or patch available at this time.

An attacker with Administrator-level access can upload arbitrary files to the server, which may result in remote code execution. This compromises the confidentiality, integrity, and availability of the affected system. The vulnerability could allow full control over the WordPress site and underlying server environment if exploited.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Administrator access to trusted users only and monitor for suspicious file uploads. Consider disabling or removing the vulnerable plugin if possible.
