CVE-2025-23880 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the 'anmari amr personalise' plugin, specifically affecting versions up to 2.10. CSRF vulnerabilities occur when a web application does not sufficiently verify that requests originate from legitimate users, allowing attackers to trick authenticated users into submitting unwanted actions. In this case, the plugin fails to implement proper anti-CSRF protections such as synchronizer tokens or origin checks. As a result, an attacker can craft malicious web pages or links that, when visited by an authenticated user, cause the victim's browser to send unauthorized requests to the vulnerable plugin, potentially modifying user settings or personalizing data without consent. Although no known exploits have been reported in the wild, the vulnerability is publicly disclosed and could be targeted by attackers. The lack of patches or official fixes at the time of disclosure increases the urgency for organizations to implement interim mitigations. The vulnerability impacts the integrity of user data and may also affect confidentiality if sensitive personalization data is altered or exposed. Exploitation requires the victim to be logged in and to interact with attacker-controlled content, which is a common attack vector in web environments. The plugin is used primarily in WordPress ecosystems, which are widespread globally, increasing the scope of affected systems. The absence of a CVSS score necessitates an expert severity assessment based on the vulnerability's characteristics.

The primary impact of CVE-2025-23880 is the unauthorized execution of actions within the 'anmari amr personalise' plugin by exploiting the victim's authenticated session. This can lead to unauthorized changes in personalization settings, potentially causing data integrity issues or exposing sensitive user preferences. For organizations, this may result in compromised user trust, data manipulation, and potential downstream effects if personalization influences access controls or content delivery. Since the vulnerability requires user authentication and interaction, the attack surface is limited to active users, but the ease of exploitation via social engineering or malicious websites increases risk. The lack of known exploits currently limits immediate widespread impact, but the public disclosure may prompt attackers to develop exploits. Organizations relying on this plugin for user personalization in their web applications face risks of targeted attacks that could disrupt user experience or lead to further exploitation if combined with other vulnerabilities. The vulnerability does not directly affect availability but could indirectly cause service disruption if exploited at scale or combined with other attack vectors.

To mitigate CVE-2025-23880, organizations should first monitor for official patches or updates from the 'anmari' vendor and apply them promptly once available. In the interim, implement strict anti-CSRF protections by integrating synchronizer tokens or verifying the HTTP Referer and Origin headers for all state-changing requests within the plugin. Review and harden user session management to limit the impact of forged requests. Educate users about the risks of interacting with untrusted websites while authenticated on critical systems. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious CSRF attempts targeting the plugin endpoints. Conduct thorough code reviews and penetration testing focused on CSRF vectors in the affected plugin. If feasible, temporarily disable or replace the plugin with alternatives that have robust security controls until a patch is available. Additionally, implement Content Security Policy (CSP) headers to reduce the risk of malicious content injection and limit the ability of attackers to host malicious CSRF payloads.
