CVE-2025-62941 identifies a Stored Cross-Site Scripting (XSS) vulnerability in the Events Maker plugin by dFactory, a WordPress plugin used for event management. The vulnerability stems from improper neutralization of input during web page generation, meaning that user-supplied data is not adequately sanitized or encoded before being rendered in the HTML output. This allows an attacker with low privileges (PR:L) to inject malicious JavaScript code that is stored persistently within the application and executed in the context of other users who view the affected pages. The CVSS vector indicates network attack vector (AV:N), low attack complexity (AC:L), privileges required are low (PR:L), user interaction is required (UI:R), and the scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact affects confidentiality and integrity partially (C:L/I:L) but does not affect availability (A:N). Stored XSS can lead to session hijacking, defacement, or unauthorized actions performed on behalf of legitimate users. Although no exploits are currently known in the wild, the vulnerability is publicly disclosed and should be addressed promptly. The affected versions include all releases up to and including 1.6.14 of the Events Maker plugin. No official patches or updates are linked yet, but monitoring vendor advisories is critical. The vulnerability is particularly relevant to organizations using WordPress for event management, where user-generated content is common and can be exploited to inject malicious scripts.

For European organizations, the impact of this vulnerability can be significant, especially for those relying on the Events Maker plugin for managing events, registrations, or community interactions on their WordPress sites. Exploitation could allow attackers to steal session cookies, impersonate users, or perform unauthorized actions within the affected web application, potentially leading to data leakage or manipulation of event data. This could damage organizational reputation, lead to regulatory non-compliance (e.g., GDPR breaches if personal data is exposed), and disrupt business operations. Since the vulnerability requires low privileges but user interaction, phishing or social engineering could be used to lure users into triggering the exploit. The scope change means that the attacker could affect components beyond the plugin itself, increasing the risk. The medium severity indicates a moderate threat level, but the widespread use of WordPress and event management plugins in Europe heightens the risk profile. Organizations in sectors such as education, public administration, and event management are particularly vulnerable.

1. Monitor for official patches or updates from dFactory and apply them immediately once available to remediate the vulnerability. 2. In the interim, restrict plugin usage to trusted users and limit the ability to submit or edit event content to minimize attack surface. 3. Implement robust input validation and output encoding on all user-supplied data related to event creation or editing, ensuring that scripts or HTML tags are properly sanitized. 4. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. 5. Educate users about phishing and social engineering risks to reduce the likelihood of user interaction exploitation. 6. Conduct regular security audits and vulnerability scans focusing on web application inputs and plugin components. 7. Consider using Web Application Firewalls (WAF) with rules designed to detect and block XSS payloads targeting WordPress plugins. 8. Review and limit plugin permissions and roles within WordPress to enforce the principle of least privilege.
