A flaw was found in Keycloak. A realm administrator with the "manage-realm" role can exploit this vulnerability by submitting an arbitrary filesystem path as a keystore parameter when creating a key provider component. This allows the administrator to probe arbitrary filesystem paths, determining which files exist and are readable by the Keycloak process. This information disclosure could be used to identify high-value targets for follow-on attacks.

The Smart Slider 3 plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 3.5.1.36 via the replaceHTMLImage function. This makes it possible for authenticated attackers, with administrator-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.

Multiple authenticated path traversal vulnerabilities exist in the Aruba EdgeConnect Enterprise command line interface. Successful exploitation of these vulnerabilities result in the ability to read arbitrary files on the underlying operating system, including sensitive system files.

The LearnPress – Backup & Migration Tool plugin for WordPress is vulnerable to Arbitrary File Read via Directory Traversal in all versions up to, and including, 4.1.4 via the 'import-user-file' parameter parameter. This makes it possible for authenticated attackers, with administrator-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.

The Woosa – Marktplaats for WooCommerce plugin for WordPress is vulnerable to Arbitrary File Read via Path Traversal in versions up to and including 2.0.4. This is due to insufficient path sanitization in the render_logs_ui() function, which accepts a base64-encoded file name from the 'log_file' GET parameter and concatenates it directly with the plugin's log directory path without validating that the resolved path remains within the intended directory. This makes it possible for authenticated attackers, with Administrator-level access, to read the contents of arbitrary files on the server, including wp-config.

Multiple authenticated path traversal vulnerabilities exist in the Aruba EdgeConnect Enterprise command line interface. Successful exploitation of these vulnerabilities result in the ability to read arbitrary files on the underlying operating system, including sensitive system files.

Pimcore is an open source data and experience management platform. Prior to version 10.5.21, the `/admin/misc/script-proxy` API endpoint that is accessible by an authenticated administrator user is vulnerable to arbitrary JavaScript and CSS file read via the `scriptPath` and `scripts` parameters. The `scriptPath` parameter is not sanitized properly and is vulnerable to path traversal attack. Any JavaScript/CSS file from the application server can be read by specifying sufficient number of `../` patterns to go out from the application webroot followed by path of the folder where the file is located in the "scriptPath" parameter and the file name in the "scripts" parameter. The JavaScript file is successfully read only if the web application has read access to it. Users should update to version 10.5.21 to receive a patch or, as a workaround, apply the patch manual.

An improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability [CWE-22] in Fortinet FortiManager version 7.4.0 through 7.4.2 and below 7.2.5, FortiAnalyzer version 7.4.0 through 7.4.2 and below 7.2.5 & FortiAnalyzer-BigData version 7.4.0 and below 7.2.7 allows a privileged attacker to read arbitrary files from the underlying system via crafted HTTP or HTTPs requests.

flarum is a forum software package for building communities. In versions prior to 1.7.0 an admin account which has already been compromised by an attacker may use a vulnerability in the `LESS` parser which can be exploited to read sensitive files on the server through the use of path traversal techniques. An attacker can achieve this by providing an absolute path to a sensitive file in the custom `LESS` setting, which the `LESS` parser will then read. For example, an attacker could use the following code to read the contents of the `/etc/passwd` file on a linux machine. The scope of what files are vulnerable will depend on the permissions given to the running flarum process. The vulnerability has been addressed in version `1.7`. Users should upgrade to this version to mitigate the vulnerability. Users unable to upgrade may mitigate the vulnerability by ensuring that their admin accounts are secured with strong passwords and follow other best practices for account security. Additionally, users can limit the exposure of sensitive files on the server by implementing appropriate file permissions and access controls at the operating system level.

The WordPress File Upload and WordPress File Upload Pro plugins for WordPress are vulnerable to Path Traversal in versions up to, and including, 4.19.1 via the vulnerable parameter wfu_newpath. This allows administrator-level attackers to move files uploaded with the plugin (located in wp-content/uploads by default) outside of the web root.

OpenWrt is a Linux operating system targeting embedded devices. Prior to 25.12.5, the cgi-download handler in cgi-io authorizes the requested path against the caller's ubus session file ACL before canonicalization, and rpcd session.c uses fnmatch() without FNM_PATHNAME, allowing traversal such as an allowed wildcard prefix followed by ../ to read root-readable files including /etc/shadow. This vulnerability is fixed in 25.12.5.
