CVE-2025-4419 is a path traversal vulnerability identified in the Hot Random Image plugin for WordPress, developed by hotwptemplates. This vulnerability affects all versions up to and including 1.9.2. The flaw exists in the handling of the 'path' parameter, which is improperly validated, allowing authenticated users with Contributor-level access or higher to traverse directories outside the intended image directory. Specifically, attackers can manipulate the 'path' parameter to access arbitrary image files with allowed extensions located anywhere on the server's filesystem. This vulnerability is classified under CWE-22, which involves improper limitation of a pathname to a restricted directory, leading to unauthorized file access. The CVSS v3.1 base score is 4.3 (medium severity), reflecting that the attack vector is network-based, requires low attack complexity, and privileges at the level of a Contributor or above, but does not require user interaction. The impact is limited to confidentiality as attackers can read image files outside the intended directory but cannot modify or delete files, nor cause denial of service. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is significant because WordPress is widely used, and plugins like Hot Random Image are common for managing media content, making this a relevant concern for websites relying on this plugin for image display and management.

For European organizations, this vulnerability poses a moderate confidentiality risk. Attackers with Contributor-level access—typically users who can add and edit content but not publish—could exploit this flaw to access sensitive image files stored outside the intended directories. While this does not directly lead to code execution or system compromise, unauthorized access to images could expose sensitive information, such as internal documents scanned as images, personal data embedded in images, or proprietary visual content. This could lead to privacy violations under GDPR if personal data is exposed, resulting in regulatory penalties and reputational damage. Additionally, attackers might use the information gathered from accessible files to facilitate further attacks. The impact is more pronounced for organizations with multiple contributors or less stringent user access controls. Since the vulnerability does not allow modification or deletion of files, the integrity and availability of systems remain unaffected. However, the ease of exploitation by authenticated users means insider threats or compromised contributor accounts could be leveraged to exploit this vulnerability.

To mitigate this vulnerability, European organizations should first verify if they use the Hot Random Image plugin and identify the version in use. Immediate steps include: 1) Restrict Contributor-level user permissions by auditing and minimizing the number of users with such access, ensuring only trusted personnel have these roles. 2) Implement strict input validation and sanitization for the 'path' parameter within the plugin code if custom modifications are possible, or apply virtual patching via Web Application Firewalls (WAFs) to detect and block path traversal patterns. 3) Monitor web server logs for suspicious requests containing directory traversal sequences (e.g., '../') targeting the plugin endpoints. 4) Until an official patch is released, consider disabling or replacing the plugin with alternative solutions that do not have this vulnerability. 5) Employ file system permissions to restrict the web server’s access to sensitive directories and files outside the intended image directories, limiting the impact of any traversal attempts. 6) Educate content contributors about security best practices and the risks of credential compromise. These targeted actions go beyond generic advice by focusing on user role management, input validation, monitoring, and access control specific to this vulnerability.
