CVE-2025-8676 is a vulnerability classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) found in the B Slider- Gutenberg Slider Block for WordPress plugin, specifically in versions up to and including 2.0.0. The vulnerability arises from the get_active_plugins function, which improperly exposes details about installed plugins to authenticated users with subscriber-level privileges or higher. This exposure allows these users to enumerate active plugins, revealing potentially sensitive information that could assist attackers in identifying further vulnerabilities within the WordPress environment. The vulnerability requires authentication but no additional user interaction, and it can be exploited remotely over the network. The CVSS v3.1 base score is 4.3, indicating a medium severity level primarily due to the confidentiality impact without affecting integrity or availability. No patches or fixes are currently linked, and no known exploits have been reported in the wild. The vulnerability is significant because plugin enumeration can be a critical step in targeted attacks, enabling adversaries to tailor exploits against known vulnerable plugins or versions. The affected product is widely used in WordPress sites that implement the B Slider- Gutenberg Slider Block, a popular slider block plugin for content presentation. The vulnerability disclosure date is August 15, 2025, and it is assigned by Wordfence.

The primary impact of CVE-2025-8676 is the unauthorized disclosure of sensitive information regarding installed plugins on WordPress sites using the vulnerable B Slider plugin. This information leakage can facilitate reconnaissance by attackers, enabling them to identify vulnerable plugins or outdated versions to exploit further. Although the vulnerability does not directly compromise data integrity or availability, the confidentiality breach increases the risk of subsequent attacks such as privilege escalation, remote code execution, or site defacement if other vulnerabilities exist in the disclosed plugins. Organizations relying on this plugin may face increased risk of targeted attacks, especially if they do not have robust monitoring or patch management processes. The requirement for authenticated access limits the attack surface to users who already have some level of access, but subscriber-level permissions are common and often granted to many users, including those with minimal privileges. This makes the vulnerability relevant for multi-user WordPress environments such as membership sites, blogs with multiple contributors, or e-commerce platforms. The absence of known exploits in the wild suggests limited active exploitation currently, but the information exposure could be leveraged by attackers to develop targeted exploits. Overall, the impact is moderate but could be a stepping stone for more severe attacks if combined with other vulnerabilities.

To mitigate CVE-2025-8676, organizations should first verify if they are using the B Slider- Gutenberg Slider Block for WordPress plugin at version 2.0.0 or earlier. Since no patch links are currently available, administrators should consider the following specific actions: 1) Restrict subscriber-level and higher user permissions to trusted individuals only, minimizing the number of users who can exploit this information leak. 2) Implement strict role-based access controls and audit user accounts regularly to detect unauthorized privilege escalations. 3) Employ web application firewalls (WAFs) with custom rules to monitor and block suspicious requests targeting the get_active_plugins function or related plugin enumeration attempts. 4) Monitor WordPress logs and plugin activity for unusual access patterns or attempts to enumerate plugins. 5) Consider temporarily disabling or replacing the vulnerable plugin with alternative slider plugins that do not expose sensitive information. 6) Stay updated with vendor advisories and apply patches promptly once available. 7) Harden the WordPress environment by disabling unnecessary REST API endpoints or functions that expose plugin data to authenticated users. These targeted mitigations go beyond generic advice by focusing on access control, monitoring, and proactive plugin management specific to this vulnerability.
