elFinder is an open-source file manager for web, written in JavaScript using jQuery UI. Several vulnerabilities affect elFinder 2.1.58. These vulnerabilities can allow an attacker to execute arbitrary code and commands on the server hosting the elFinder PHP connector, even with minimal configuration. The issues were patched in version 2.1.59. As a workaround, ensure the connector is not exposed without authentication.

A File Upload vulnerability exists in Studio-42 elFinder 2.0.4 to 2.1.59 via connector.minimal.php, which allows a remote malicious user to upload arbitrary files and execute PHP code.

elFinder before 2.1.48 has a command injection vulnerability in the PHP connector.

_joinPath in elFinderVolumeLocalFileSystem.class.php in elFinder before 2.1.62 allows path traversal in the PHP LocalVolumeDriver connector.

In Studio-42 elFinder 2.1.60, there is a vulnerability that causes remote code execution through file name bypass for file upload.

connector.minimal.php in std42 elFinder through 2.1.60 is affected by path traversal. This allows unauthenticated remote attackers to read, write, and browse files outside the configured document root. This is due to improper handling of absolute file paths.

Studio 42 elFinder through 2.1.31 allows XSS via an SVG document.

The package studio-42/elfinder before 2.1.58 are vulnerable to Remote Code Execution (RCE) via execution of PHP code in a .phar file. NOTE: This only applies if the server parses .phar files as PHP.

A Server Side Request Forgery (SSRF) vulnerability in elFinder before 2.1.46 could allow a malicious user to access the content of internal network resources. This occurs in get_remote_contents() in php/elFinder.class.php.

php/elFinder.class.php in elFinder before 2.1.45 leaks information if PHP's curl extension is enabled and safe_mode or open_basedir is not set.
