CVE-2025-62941 identifies a Stored Cross-site Scripting (XSS) vulnerability in the Events Maker plugin developed by dFactory, affecting all versions up to and including 1.6.14. The vulnerability stems from improper neutralization of user-supplied input during the generation of web pages, which allows malicious scripts to be stored persistently within the plugin's data fields. When a victim accesses a compromised page, the injected script executes in their browser context, potentially leading to session hijacking, credential theft, unauthorized actions, or malware distribution. Stored XSS is particularly dangerous because the malicious payload is saved on the server and served to multiple users, increasing the attack surface. The vulnerability does not require authentication, meaning any unauthenticated attacker can exploit it by submitting crafted input. No CVSS score has been assigned yet, and no public exploits have been reported, but the nature of stored XSS vulnerabilities makes them a common target for attackers. The plugin is widely used in WordPress environments for event management, which are common in organizational websites. The lack of available patches at the time of publication necessitates immediate attention to mitigation strategies. The vulnerability's presence in a popular plugin increases the likelihood of exploitation attempts, especially in sectors relying on event scheduling and management. The technical root cause is the failure to properly sanitize or encode input before embedding it into HTML output, violating secure coding practices and enabling script injection.

For European organizations, exploitation of this vulnerability could lead to significant security incidents including theft of user credentials, unauthorized access to sensitive information, defacement of public-facing event pages, and distribution of malware to site visitors. This can damage organizational reputation, lead to regulatory non-compliance (e.g., GDPR breaches due to data exposure), and disrupt business operations. Since the plugin is used in event management, attacks could also interfere with event scheduling and communications, impacting customer engagement and operational workflows. The stored nature of the XSS means multiple users can be affected, amplifying the potential damage. Organizations with high web traffic and public-facing event platforms are particularly at risk. Additionally, attackers could leverage the vulnerability as a foothold for further network compromise or lateral movement within the organization’s infrastructure. The absence of known exploits currently provides a window for proactive defense, but the risk of future exploitation remains high.

1. Immediately update the Events Maker plugin to a patched version once available from dFactory. 2. Until a patch is released, disable or restrict user input fields that accept event data to trusted users only. 3. Implement web application firewall (WAF) rules to detect and block common XSS payloads targeting the plugin’s input fields. 4. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in browsers. 5. Conduct thorough input validation and output encoding on all user-supplied data related to event creation and display. 6. Monitor web server and application logs for suspicious input patterns or unusual activity related to the plugin. 7. Educate site administrators and users about the risks of XSS and encourage vigilance when interacting with event content. 8. Consider isolating or sandboxing the plugin’s functionality to minimize impact if exploited. 9. Regularly back up website data to enable quick restoration in case of defacement or compromise. 10. Engage with dFactory support channels to receive timely updates and security advisories.
