CVE-2025-62987 is a stored cross-site scripting (XSS) vulnerability identified in the Builderall Builder for WordPress plugin, specifically affecting versions up to and including 3.0.1. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows an attacker to inject malicious scripts that are stored persistently within the application. When other users or administrators view the affected pages, the malicious scripts execute in their browsers, potentially leading to session hijacking, defacement, or redirection to malicious sites. The vulnerability requires the attacker to have at least low privileges (PR:L) and user interaction (UI:R), such as tricking an administrator or user into viewing a crafted page. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) indicates network attack vector, low attack complexity, partial scope change, and low impact on confidentiality, integrity, and availability. No public exploits are currently known, but the vulnerability is significant due to the widespread use of WordPress and the Builderall plugin for website building. The lack of a patch link suggests that a fix may not yet be available, emphasizing the need for interim mitigations.

For European organizations, the impact of this vulnerability can be substantial, particularly for those relying on the Builderall Builder plugin for their WordPress sites. Successful exploitation could allow attackers to execute arbitrary JavaScript in the context of the affected site, leading to theft of session cookies, user credentials, or other sensitive information. This could result in unauthorized access to administrative functions, data leakage, or further compromise of the web server. Additionally, attackers could deface websites or redirect visitors to malicious domains, damaging brand reputation and customer trust. Given the partial scope change, the vulnerability could affect multiple users or components beyond the initially compromised user. The medium CVSS score reflects a moderate risk, but the real-world impact depends on the site's role and the sensitivity of the data it handles. European organizations with e-commerce, financial, or government-facing websites are particularly at risk due to the potential for data breaches and regulatory consequences under GDPR.

1. Monitor Builderall's official channels for security updates and apply patches immediately once available. 2. Until a patch is released, restrict plugin usage to trusted users only, minimizing the number of users with privileges to input content that could be exploited. 3. Implement Web Application Firewall (WAF) rules to detect and block common XSS payloads targeting the Builderall plugin. 4. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on affected sites. 5. Conduct regular security audits and code reviews of custom content added via the plugin to detect suspicious inputs. 6. Educate administrators and users about the risks of clicking on untrusted links or viewing unverified content within the WordPress admin interface. 7. Consider temporarily disabling or replacing the Builderall plugin if patching is delayed and risk is deemed unacceptable. 8. Use security plugins that sanitize inputs and outputs to add an additional layer of protection against XSS.
