CVE-2025-68591 identifies a missing authorization vulnerability in the Simple File List plugin developed by Mitchell Bennis, which is widely used for managing and displaying file lists on websites. The vulnerability arises from incorrectly configured access control security levels, allowing unauthorized users to bypass restrictions and access file listings that should be protected. This flaw affects all versions up to and including 6.1.15. The core issue is that the plugin fails to properly verify user permissions before granting access to file lists, which can lead to exposure of sensitive or confidential files hosted on the affected web servers. Although no exploits have been reported in the wild yet, the nature of the vulnerability—missing authorization checks—makes it relatively straightforward for attackers to exploit, especially since no authentication is required. The vulnerability impacts the confidentiality and integrity of data by allowing unauthorized disclosure and potential manipulation of file listings. The lack of a CVSS score means severity must be assessed based on the potential impact and exploitability. The vulnerability is particularly relevant for organizations using the Simple File List plugin in environments where sensitive data is stored or shared. Since the plugin is commonly used in WordPress environments, the attack surface includes numerous websites and web applications. The vulnerability was published on December 24, 2025, with no patch links currently available, emphasizing the need for vigilance and proactive mitigation.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive files managed via the Simple File List plugin. Unauthorized access could lead to data leaks, intellectual property theft, or exposure of personal data, potentially violating GDPR and other data protection regulations. The absence of authentication requirements lowers the barrier for attackers, increasing the likelihood of exploitation. Organizations in sectors such as finance, healthcare, legal, and government, which often handle sensitive documents, are particularly vulnerable. Additionally, reputational damage and regulatory penalties could result from breaches stemming from this vulnerability. The impact extends to operational disruption if attackers manipulate or delete files, affecting business continuity. Since the plugin is often integrated into WordPress sites, which are prevalent in Europe, the scope of affected systems is broad. The vulnerability could also be leveraged as a foothold for further attacks within compromised networks.

1. Monitor for official patches or updates from Mitchell Bennis and apply them immediately upon release. 2. In the absence of patches, restrict access to the Simple File List plugin directories using web server configuration (e.g., .htaccess rules) to limit exposure to trusted IP addresses or authenticated users only. 3. Review and harden access control settings within the plugin, ensuring that file listings are not publicly accessible unless explicitly intended. 4. Implement web application firewalls (WAF) with rules to detect and block unauthorized access attempts targeting the plugin endpoints. 5. Conduct regular audits of file access logs to identify suspicious activity related to the plugin. 6. Educate website administrators and developers about the risks of misconfigured access controls and encourage security best practices. 7. Consider alternative secure file listing solutions if immediate patching is not feasible. 8. Employ network segmentation to isolate web servers hosting the plugin from sensitive internal systems to limit lateral movement if exploited.
