CVE-2026-4808 tidevapps CVE debrief

Who should care

Administrators and users with Administrator-level access and above on WordPress sites using the Gerador de Certificados – DevApps plugin should be aware of this vulnerability. They should review their current plugin version, assess potential exposure, and implement necessary security measures to prevent exploitation.

Technical summary

The Gerador de Certificados – DevApps plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the moveUploadedFile() function in all versions up to, and including, 1.3.6. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. The vulnerability's technical impact involves potential code execution through uploaded malicious files, highlighting the importance of restricting file uploads and monitoring server activity.

Defensive priority

High priority due to the potential for remote code execution and the relatively high CVSS score of 7.2.

Recommended defensive actions

• Update the Gerador de Certificados – DevApps plugin to a version beyond 1.3.6.
• Restrict file uploads to only allow specific file types.
• Monitor server logs for suspicious file upload activity.
• Implement additional security measures such as Web Application Firewalls (WAFs).
• Regularly review and update plugins and themes.
• Perform vulnerability scanning and penetration testing to identify potential weaknesses.
• Establish incident response plans in case of successful exploitation.

Evidence notes

Evidence from the CVE record and NVD detail indicate a high severity vulnerability with a CVSS score of 7.2. The vulnerability allows for arbitrary file uploads which could lead to remote code execution. However, specific details about the vulnerability, such as the exact nature of the file type validation bypass and potential mitigations, are limited in the provided sources. Further verification and review of the plugin's code and security advisories are recommended.
