Live › vulnerability › CVE-2026-111311
Go to dashboardThe DoubleScale All-in-One CRM plugin for WordPress accepts uploads of files such as .php because its extension check fails open for unrecognized extensions. Any logged-in user with subscriber-level access or higher can upload an executable file, which can lead to remote code execution on the site server.

The DoubleScale | All-in-One CRM – Sales, Multi-Channel Marketing, Newsletter, Booking, Helpdesk, Automation, MCP & More plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.5.1 via the store_upload function. This is due to a fail-open extension allow-list in extension_is_allowed() that returns true when wp_check_filetype() yields an empty type for unrecognized extensions such as .php, combined with magic-byte-only MIME detection and no capability check beyond is_user_logged_in(). This makes it possible for authenticated attackers, with subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible. Exploitation requires the Helpdesk module to be enabled, as the vulnerable REST endpoint is only registered when that module is active.
