The vulnerability identified as CVE-2025-2006 affects the Inline Image Upload for BBPress plugin for WordPress, specifically all versions up to 1.1.19. The root cause is the absence of proper file extension validation during the file upload process, categorized under CWE-434 (Unrestricted Upload of File with Dangerous Type). This allows attackers with at least Subscriber-level privileges to upload arbitrary files to the server hosting the WordPress site. Uploaded files could include malicious scripts that enable remote code execution (RCE), potentially allowing attackers to execute arbitrary commands, escalate privileges, or take full control of the server. Furthermore, if the plugin's setting "Allow guest users without accounts to create topics and replies" is enabled, unauthenticated attackers can exploit this vulnerability, significantly broadening the attack surface. The vulnerability has a CVSS v3.1 base score of 8.8, indicating high severity with network attack vector, low attack complexity, privileges required (low-level user), no user interaction, and impacts on confidentiality, integrity, and availability. Although no known exploits are currently in the wild, the ease of exploitation and potential impact make this a critical concern for WordPress sites using this plugin. The vulnerability remains unpatched as of the publication date, and no official patch links are provided, emphasizing the need for immediate attention.

The impact of CVE-2025-2006 is significant for organizations running WordPress sites with the Inline Image Upload for BBPress plugin. Successful exploitation can lead to remote code execution, allowing attackers to execute arbitrary commands on the server, potentially leading to full system compromise. This can result in data breaches, defacement, malware deployment, or use of the compromised server as a pivot point for further attacks within the network. Confidentiality is at risk due to unauthorized data access, integrity is compromised by potential unauthorized modifications, and availability can be affected if attackers disrupt services or deploy ransomware. The ability for unauthenticated users to exploit the vulnerability when guest posting is enabled increases the risk for public-facing forums and community sites. Organizations relying on this plugin without proper controls or patches face elevated risks of cyberattacks, data loss, reputational damage, and regulatory penalties.

To mitigate CVE-2025-2006, organizations should immediately audit their WordPress installations for the Inline Image Upload for BBPress plugin and verify the version in use. If possible, upgrade to a patched version once released by the vendor. In the absence of an official patch, administrators should disable the plugin or the vulnerable file upload functionality temporarily. Additionally, disable the "Allow guest users without accounts to create topics and replies" setting to prevent unauthenticated exploitation. Implement strict web application firewall (WAF) rules to block suspicious file uploads and monitor upload directories for unauthorized files. Employ file integrity monitoring to detect unexpected changes. Restrict file permissions on upload directories to prevent execution of uploaded scripts. Regularly review user roles and permissions to minimize the number of users with upload capabilities. Finally, maintain comprehensive backups and incident response plans to recover quickly in case of compromise.
