CVE-2025-66060 identifies a missing authorization vulnerability in the Seriously Simple Podcasting plugin developed by Craig Hewitt, affecting versions up to and including 3.13.0. The vulnerability stems from incorrectly configured access control security levels, which fail to properly restrict unauthorized users from performing certain actions within the plugin. This could allow attackers to bypass intended permission checks, potentially leading to unauthorized modification, deletion, or disclosure of podcast-related data. The plugin is widely used in WordPress environments to manage podcast content, making it a valuable target for attackers seeking to manipulate media assets or disrupt content delivery. Although no exploits have been observed in the wild, the vulnerability’s presence in a popular plugin increases the risk of future exploitation. The lack of a CVSS score suggests that the vulnerability was recently disclosed and not yet fully assessed. The vulnerability does not appear to require user interaction, and exploitation feasibility depends on the attacker’s ability to reach the vulnerable plugin interface. The issue highlights the importance of proper authorization checks in web applications, especially plugins that extend CMS functionality. Organizations relying on Seriously Simple Podcasting should monitor for patches and review their WordPress security configurations to prevent unauthorized access.

For European organizations, the impact of CVE-2025-66060 could be significant, particularly for media companies, broadcasters, and content creators using the Seriously Simple Podcasting plugin. Unauthorized access could lead to manipulation or deletion of podcast episodes, compromising content integrity and availability. Confidentiality risks arise if sensitive unpublished content or metadata is exposed. Disruption to podcast services could damage brand reputation and user trust. Since WordPress powers a substantial portion of European websites, and podcasting is a growing medium, the scope of affected systems is considerable. The vulnerability could also be leveraged as a foothold for further attacks within the hosting environment, potentially escalating to broader compromise. The absence of known exploits currently limits immediate risk, but the potential for future exploitation necessitates proactive measures. The impact is heightened in organizations with limited WordPress security expertise or those that delay plugin updates.

Organizations should immediately inventory their WordPress installations to identify the presence of Seriously Simple Podcasting plugin versions up to 3.13.0. Until an official patch is released, restrict access to the WordPress admin interface and plugin endpoints using web application firewalls or IP whitelisting to reduce exposure. Implement strict role-based access controls within WordPress to limit plugin management capabilities to trusted administrators only. Monitor logs for unusual activity related to podcast content management. Regularly backup podcast data and WordPress configurations to enable rapid recovery if exploitation occurs. Once a patch is available, apply it promptly and verify that authorization checks are enforced correctly. Additionally, conduct security audits of other installed plugins to detect similar misconfigurations. Educate content management teams about the risks of unauthorized access and establish incident response plans tailored to CMS-related threats.
