VU#162329: Multiple vulnerabilities in Thelia 2.6.0 and 2.6.1
CVE-2026-103521CVE-2026-103522rcexss
Overview Thelia versions 2.6.0 and 2.6.1 contain multiple vulnerabilities relating to file management, Smarty templating, module installation, and administrative workflows. Successful exploitation of these issues could enable remote code execution (RCE), server-side template injection (SSTI), stored and reflected cross-site scripting (XSS), unauthorized URL redirection, and other risks that expose both server-side and client-side attack surfaces. Description Thelia is an open-source e-commerce platform designed to provide merchants with customizable online storefronts, product management workflows, and administrative functionalities. It utilizes the Smarty template engine and provides administrators with broad control over templates, content, and modules. CVE-2026-103521 In Thelia v2.6.0, the document upload endpoint properly blocks the upload of executable file types, but the document update endpoint does not perform the same validation. An attacker with administrative Thelia permissions can exploit this vulnerability to upload arbitrary executable files, such as malicious PHP scripts, to achieve remote code execution on the underlying server. CVE-2026-103522 In Thelia v2.6.0, the store banner upload feature performs insufficient filetype validation that relies exclusively on client-supplied MIME types. An attacker with administrative access can upload a PHP file disguised as an image to bypass validation and achieve remote code execution on the underlying server. CVE-2026-1
