CVE-2025-57983 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the WordPress plugin 'BP Disable Activation Reloaded' developed by Damian. This vulnerability arises due to improper constraints on access control lists (ACLs) for certain functionalities within the plugin, allowing an attacker to trick an authenticated user into executing unwanted actions without their consent. Specifically, the vulnerability affects versions up to 1.2.1 of the plugin. The CVSS 3.1 base score is 6.5 (medium severity), with the vector indicating that the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), requires no privileges (PR:N), but does require user interaction (UI:R). The impact is primarily on integrity (I:H), meaning an attacker can cause unauthorized changes or actions within the affected system, but confidentiality and availability are not impacted. No known exploits are currently in the wild, and no patches have been published yet. The vulnerability is categorized under CWE-352, which involves CSRF attacks that exploit the trust a web application places in the user's browser. Since the plugin is designed to disable activation features in BuddyPress (a social networking plugin for WordPress), the vulnerability could allow attackers to manipulate user account activation or related workflows, potentially leading to unauthorized changes in user states or configurations. This could be leveraged for further attacks or to disrupt normal user management processes.

For European organizations, especially those using WordPress with BuddyPress and the BP Disable Activation Reloaded plugin, this vulnerability poses a risk of unauthorized actions being performed on their websites. This could lead to integrity violations such as unauthorized activation or deactivation of user accounts or modification of user-related settings. While the vulnerability does not directly compromise confidentiality or availability, the unauthorized changes could facilitate social engineering, privilege escalation, or other indirect attacks. Organizations relying on community engagement platforms or social networking features on their websites may face reputational damage if user accounts are manipulated. Additionally, attackers could exploit this vulnerability to bypass intended access controls, potentially affecting compliance with data protection regulations like GDPR if user data integrity is compromised. The lack of a patch increases the window of exposure, and the requirement for user interaction means phishing or social engineering campaigns could be used to exploit this vulnerability.

1. Immediate mitigation should include disabling or removing the BP Disable Activation Reloaded plugin until a patch is released. 2. Implement strict Content Security Policy (CSP) headers to reduce the risk of CSRF attacks by limiting the sources of executable scripts. 3. Employ anti-CSRF tokens in all state-changing requests within the web application, ensuring that any action requires a valid token that an attacker cannot forge. 4. Educate users and administrators about the risks of clicking on suspicious links or performing actions prompted by untrusted sources to reduce the risk of social engineering exploitation. 5. Monitor web server logs for unusual POST requests or suspicious referrer headers that could indicate attempted CSRF attacks. 6. Once a patch is available, promptly apply it and verify that the plugin properly enforces ACLs and CSRF protections. 7. Consider implementing Web Application Firewalls (WAF) with rules to detect and block CSRF attack patterns targeting this plugin. 8. Review and tighten user roles and permissions related to BuddyPress and the plugin to minimize the impact of potential exploitation.
