CVE-2026-38526 Details
Description
An authenticated arbitrary file upload vulnerability in the /admin/tinymce/upload endpoint of Webkul Krayin CRM v2.2.x allows attackers to execute arbitrary code via uploading a crafted PHP file.
A vulnerability exists in Webkul Krayin CRM version 2.2.x, allowing authenticated users to upload arbitrary files through the TinyMCE upload endpoint. The application fails to properly validate file types, enabling the upload of malicious PHP files that can be executed on the server, leading to remote code execution.
Users are advised to implement file type validation to restrict uploads to safe MIME types and extensions, store uploaded files outside the web root, rename files to random UUIDs with safe extensions, disable PHP execution in upload directories if files must remain web-accessible, and review authentication requirements for the TinyMCE upload endpoint.
