9.8 · CRITICALOverview
CVE-2026-41247 is a critical-severity vulnerability affecting std42 elfinder. It was published on April 23, 2026 and has a CVSS 3.1 base score of 9.8 (CRITICAL).
This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Prior to 2.1.67, elFinder contains a command injection vulnerability in the resize command. The bg (background color) parameter is accepted from user input and passed through image resize/rotate processing. In configurations that use the ImageMagick CLI backend, this value is incorporated into shell command strings without sufficient escaping. An attacker able to invoke the resize command with a crafted bg value may achieve arbitrary command execution as the web server process user. This vulnerability is fixed in 2.1.67.
Remediation
Check the references section for vendor advisories and patches from std42. Update elfinder to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
