CVE-2026-57827 Details
Description
Joomla Extension - rsjoomla.com - Unauthenticated file upload in RSFiles component < 1.17.12 - The Joomla extension RSFiles is vulnerable to an unauthenticated arbitrary file upload that allows uploading executable files and leads to full RCE.
A vulnerability in the RSFiles extension for Joomla allows unauthenticated users to upload arbitrary files, including executable PHP scripts, which can then be executed on the server. This issue is present in versions of RSFiles through 1.17.11 and was discovered during a source code audit. The vulnerability arises because the file upload functionality does not properly validate file types or enforce permissions, allowing malicious users to exploit the flaw and gain remote code execution on the server.
Users are advised to update RSFiles to version 1.17.12 or later. If immediate updating is not possible, the vulnerable upload controller file can be deleted to prevent exploitation.
