CVE-2025-57931 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Ays Pro Popup box plugin, affecting versions up to 5.5.4. CSRF vulnerabilities occur when a web application does not adequately verify that requests modifying state originate from legitimate users, allowing attackers to craft malicious web pages or links that cause authenticated users to unknowingly perform actions. In this case, the vulnerability allows an attacker to induce state-changing requests without requiring user interaction or authentication privileges, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The vulnerability impacts the integrity of the affected system by enabling unauthorized changes but does not compromise confidentiality or availability directly. The plugin is commonly used to create popup boxes in websites, often integrated into content management systems like WordPress, making it a potential target for attackers aiming to manipulate user interactions or site behavior. No patches or exploit code are currently available, but the vulnerability is publicly disclosed and assigned a medium severity rating with a CVSS score of 5.3. The lack of authentication or user interaction requirements increases the risk of automated exploitation if attackers discover effective attack vectors. The vulnerability is categorized under CWE-352, which highlights the absence or improper implementation of anti-CSRF protections such as tokens or origin checks. Organizations using this plugin should be aware of the risk of unauthorized state changes that could affect user experience, data integrity, or site functionality.

For European organizations, the CSRF vulnerability in Ays Pro Popup box poses a moderate risk primarily to the integrity of web applications utilizing this plugin. Attackers could exploit the vulnerability to perform unauthorized actions on behalf of authenticated users, potentially leading to altered configurations, manipulated content, or unintended user interactions. While confidentiality and availability are not directly impacted, the integrity compromise could facilitate further attacks such as phishing, session hijacking, or reputation damage. Organizations in sectors with high web presence—such as e-commerce, finance, and public services—may face increased risk due to the reliance on interactive web components. The vulnerability could also undermine user trust if malicious popups or altered behaviors are triggered. Given the plugin’s integration in popular CMS platforms, the scope of affected systems could be significant, especially if updates or patches are delayed. The absence of known exploits in the wild currently limits immediate risk, but the public disclosure increases the likelihood of future exploitation attempts. European entities must consider the potential for cascading impacts if attackers leverage this vulnerability as part of multi-stage attacks targeting sensitive data or critical services.

To mitigate CVE-2025-57931, European organizations should implement the following specific measures: 1) Immediately audit web applications using the Ays Pro Popup box plugin to identify affected versions and usage contexts. 2) Apply any available patches or updates from the vendor as soon as they are released; if no patch exists, consider disabling or replacing the plugin temporarily. 3) Implement or verify the presence of anti-CSRF tokens in all state-changing requests associated with the plugin to ensure requests originate from legitimate sources. 4) Enforce strict origin and referer header validation on the server side to block unauthorized cross-origin requests. 5) Employ Content Security Policy (CSP) headers to restrict the domains allowed to execute scripts or send requests to the affected site. 6) Monitor web server logs and application behavior for unusual or unexpected requests that could indicate exploitation attempts. 7) Educate developers and administrators on secure coding practices related to CSRF prevention and regularly review third-party plugin security. 8) Consider deploying Web Application Firewalls (WAFs) with rules targeting CSRF attack patterns to provide an additional layer of defense. These steps go beyond generic advice by focusing on immediate plugin-specific actions and reinforcing overall web application security posture.
