AI Analysis
Technical Summary
CVE-2026-35164 is an unrestricted file upload vulnerability in BraveCMS-2.0, specifically in the CKEditor upload feature implemented in app/Http/Controllers/Dashboard/CkEditorController.php within the ckupload method. The method fails to validate uploaded file types and relies solely on user input, enabling authenticated users to upload malicious executable PHP scripts. Successful exploitation can result in remote code execution. This vulnerability affects BraveCMS versions prior to 2.0.6 and has been fixed in version 2.0.6.
Potential Impact
An authenticated attacker can upload arbitrary executable PHP files due to lack of file type validation, leading to remote code execution. This can compromise the confidentiality, integrity, and availability of the affected system. The CVSS v3.1 base score of 8.8 reflects high impact on confidentiality, integrity, and availability with network attack vector and low attack complexity.
