CVE-2024-8483 identifies an information exposure vulnerability in the MAS Static Content plugin for WordPress, affecting all versions up to and including 1.0.8. The flaw exists in the static_content() function, which improperly restricts access controls, allowing authenticated users with contributor-level permissions or higher to retrieve sensitive data from private static content pages. This exposure falls under CWE-200, indicating that sensitive information is disclosed to unauthorized actors. The vulnerability requires no user interaction and can be exploited remotely (AV:N) with low attack complexity (AC:L). The attacker must have some level of authenticated access (PR:L), but no elevated privileges beyond contributor. The impact is limited to confidentiality loss (C:L), with no integrity or availability impact. The vulnerability is currently unpatched, and no known exploits have been reported in the wild. Given the widespread use of WordPress and the plugin, this vulnerability poses a moderate risk to websites that rely on MAS Static Content for managing private static pages. Attackers could leverage this to gather sensitive content that might include proprietary information or user data, potentially aiding further attacks or data leaks.

The primary impact of CVE-2024-8483 is unauthorized disclosure of sensitive information from private static content pages within WordPress sites using the MAS Static Content plugin. While the attacker must have contributor-level access, this level of access is commonly granted in collaborative environments, increasing the risk of insider threats or compromised contributor accounts. Exposure of sensitive content could lead to data leakage, reputational damage, and potential compliance violations depending on the nature of the information disclosed. Since the vulnerability does not affect integrity or availability, it does not directly enable site defacement or denial of service. However, the information gained could facilitate social engineering or privilege escalation attacks. Organizations with multiple contributors or external collaborators are at higher risk. The lack of known exploits reduces immediate threat but does not eliminate the risk, especially as attackers may develop exploits once the vulnerability becomes widely known.

1. Immediately review and restrict contributor-level access to only trusted users, minimizing the number of accounts with such privileges. 2. Audit all private static content pages to ensure sensitive information is not unnecessarily stored or exposed. 3. Monitor user activity logs for unusual access patterns to static content pages. 4. Implement strict role-based access control policies within WordPress to limit exposure. 5. Regularly check for updates or patches from the MAS Static Content plugin vendor and apply them promptly once available. 6. Consider temporarily disabling the MAS Static Content plugin if sensitive content exposure risk is unacceptable and no patch is available. 7. Educate contributors about the sensitivity of static content and the importance of safeguarding credentials. 8. Employ web application firewalls (WAF) to detect and block suspicious requests targeting the static_content() function. 9. Use security plugins that can enforce additional access controls or content visibility restrictions beyond the plugin’s native capabilities.
