CVE-2025-10249 is a vulnerability identified in the Slider Revolution plugin for WordPress, a widely used tool for creating sliders and interactive content on websites. The root cause is a relative path traversal issue (CWE-23) stemming from missing capability checks on multiple plugin functions. This flaw allows authenticated users with Contributor-level privileges or higher to bypass intended access controls. Specifically, attackers can install and activate plugin add-ons, create new sliders, and crucially, download arbitrary files from the server. The vulnerability affects all versions up to and including 6.7.37. The CVSS v3.1 base score is 6.5, indicating a medium severity level, with an attack vector of network, low attack complexity, and requiring privileges but no user interaction. The impact on confidentiality is high due to arbitrary file download capabilities, although integrity and availability are not directly affected. No patches or exploit code are currently publicly available, but the vulnerability's presence in a popular plugin and the relatively low privilege required makes it a notable risk for WordPress sites using this plugin.

The primary impact of this vulnerability is unauthorized disclosure of sensitive information through arbitrary file downloads, which can include configuration files, database backups, or other sensitive data stored on the web server. This can lead to data breaches, exposure of credentials, or further exploitation by attackers leveraging the obtained information. Additionally, the ability to install and activate plugin add-ons without proper authorization could allow attackers to introduce malicious code or backdoors, potentially compromising the entire website and its visitors. Organizations relying on Slider Revolution for their WordPress sites face risks to their data confidentiality and website integrity. Given the widespread use of WordPress and this plugin, the vulnerability could affect a large number of websites globally, including corporate, governmental, and e-commerce platforms.

To mitigate this vulnerability, organizations should immediately update the Slider Revolution plugin to a version that addresses this issue once released by the vendor. Until a patch is available, administrators should restrict Contributor-level and higher access to trusted users only, minimizing the risk of exploitation by malicious insiders or compromised accounts. Implementing strict role-based access controls and monitoring user activities related to plugin management can help detect and prevent unauthorized actions. Additionally, web application firewalls (WAFs) can be configured to detect and block suspicious requests attempting path traversal or unauthorized plugin operations. Regular security audits and file integrity monitoring can also help identify unauthorized changes or downloads. Finally, consider disabling or limiting plugin add-on installations if not required for business operations.
