CVE-2024-7761 is a stored Cross-Site Scripting (XSS) vulnerability identified in the Simple Job Board WordPress plugin versions prior to 2.12.2. This vulnerability arises due to insufficient input sanitization or output encoding when processing user-supplied data, specifically in the context of editor-level users embedding content. An attacker with editor privileges can inject malicious JavaScript code that is persistently stored and subsequently executed in the browsers of users who view the affected content. The exploitation of this vulnerability can lead to account takeover scenarios by leveraging the victim's authenticated session, enabling the attacker to plant backdoors or perform unauthorized actions on behalf of the compromised user. The CVSS 3.1 base score is 6.1 (medium severity), reflecting that the attack vector is network-based with low attack complexity, no privileges required, but user interaction is necessary (the victim must view the malicious content). The scope is changed, indicating that the vulnerability affects components beyond the initially vulnerable part, potentially impacting other parts of the system. While no known exploits are currently reported in the wild, the vulnerability poses a significant risk due to the potential for privilege escalation and persistent compromise within WordPress environments using this plugin. The lack of an official patch link suggests that remediation may require updating to version 2.12.2 or later once available or applying manual mitigations.

For European organizations, the impact of CVE-2024-7761 can be considerable, especially for those relying on WordPress websites with the Simple Job Board plugin to manage recruitment or job postings. Successful exploitation could lead to unauthorized access to editor accounts, enabling attackers to manipulate job listings, inject malicious content, or establish persistent backdoors. This compromises the confidentiality and integrity of organizational data and can damage reputation, particularly for companies in regulated sectors such as finance, healthcare, or government services where data protection is critical. Additionally, the presence of malicious scripts could facilitate further attacks on site visitors, including credential theft or malware distribution, amplifying the threat scope. Given the widespread use of WordPress in Europe and the importance of online recruitment platforms, this vulnerability could disrupt business operations and erode trust with applicants and partners.

To mitigate CVE-2024-7761, European organizations should prioritize updating the Simple Job Board plugin to version 2.12.2 or later as soon as it becomes available, as this is expected to contain the necessary fixes. Until then, organizations should restrict editor-level permissions to trusted users only and implement strict content moderation policies to prevent untrusted input from being embedded. Employing Web Application Firewalls (WAFs) with rules targeting XSS payloads can help detect and block exploitation attempts. Additionally, enabling Content Security Policy (CSP) headers can reduce the impact of injected scripts by restricting script execution sources. Regular security audits and scanning for malicious scripts on the website should be conducted. Monitoring user activity logs for unusual behavior can help detect potential account takeovers early. Finally, educating editors about the risks of embedding untrusted content and enforcing multi-factor authentication (MFA) for editor accounts will further reduce exploitation likelihood.
