CVE-2025-54737 is a reflected Cross-site Scripting (XSS) vulnerability found in the NooTheme Jobmonster plugin, a WordPress-based job board solution used to create recruitment websites. The vulnerability arises from improper neutralization of user-supplied input during web page generation, allowing attackers to inject malicious JavaScript code that is reflected back to users without proper sanitization or encoding. This flaw affects all versions of Jobmonster up to and including 4.7.8. An attacker can craft a malicious URL containing the payload, which when clicked by a victim, executes the script in the victim’s browser context. This can lead to theft of session cookies, defacement, or redirection to malicious sites, compromising user confidentiality and integrity, and potentially availability if the injected script disrupts site functionality. The vulnerability requires no authentication but does require user interaction to trigger the payload. The CVSS v3.1 base score is 7.1, indicating high severity, with attack vector as network, low attack complexity, no privileges required, user interaction required, and scope changed due to impact beyond the vulnerable component. No public exploits have been reported yet, but the vulnerability is publicly disclosed and should be considered a significant risk for affected sites. The lack of an official patch link suggests that users should monitor vendor updates closely or apply temporary mitigations.

For European organizations, the impact of CVE-2025-54737 can be significant, especially for those operating job board or recruitment websites using the Jobmonster plugin. Successful exploitation can lead to session hijacking, allowing attackers to impersonate users or administrators, potentially leading to unauthorized access to sensitive candidate or company data. It can also facilitate phishing attacks by redirecting users to malicious sites or injecting fraudulent content, damaging organizational reputation and trust. The integrity of the website content can be compromised, and availability may be affected if injected scripts disrupt normal operations. Given the widespread use of WordPress and its plugins in Europe, organizations in sectors such as human resources, recruitment agencies, and job portals are particularly at risk. The vulnerability could also be leveraged as a foothold for further attacks within corporate networks if administrative sessions are compromised.

1. Monitor NooTheme’s official channels for patches addressing CVE-2025-54737 and apply updates promptly once available. 2. In the interim, implement a Web Application Firewall (WAF) with robust XSS filtering rules to detect and block malicious payloads targeting the Jobmonster plugin. 3. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts on affected web pages. 4. Review and harden input validation and output encoding mechanisms within the Jobmonster plugin or custom code to ensure all user-supplied data is properly sanitized. 5. Educate users and administrators about the risks of clicking unknown or suspicious links to reduce the likelihood of successful exploitation. 6. Conduct regular security audits and penetration tests focusing on web application vulnerabilities, including XSS. 7. Consider isolating the Jobmonster plugin environment or limiting its exposure to untrusted users to reduce attack surface. 8. Backup website data regularly to enable quick recovery in case of defacement or compromise.
