CVE-2025-66059 is a vulnerability identified in the Seriously Simple Podcasting plugin developed by Craig Hewitt for WordPress. The flaw allows an unauthorized control sphere—meaning an attacker without proper permissions—to retrieve embedded sensitive system information from affected installations. This exposure could include configuration details, API keys, or other confidential data embedded within the plugin or its data structures. The vulnerability affects all versions up to and including 3.13.0, with no patch currently available or linked. The lack of authentication requirements means that any unauthenticated user visiting a vulnerable site could exploit this issue to gain sensitive information. Although no known exploits are reported in the wild, the potential for reconnaissance and subsequent targeted attacks is significant. The vulnerability primarily impacts confidentiality, as it exposes sensitive data, but could indirectly affect integrity and availability if attackers leverage the information for further compromise. The plugin is widely used in WordPress environments for podcast publishing, making the attack surface broad. The absence of a CVSS score necessitates an independent severity assessment, which considers the ease of exploitation and the sensitivity of the exposed data.

For European organizations, especially those involved in media, content creation, and podcasting, this vulnerability poses a significant risk. Exposure of sensitive system information can facilitate further attacks such as privilege escalation, data breaches, or targeted phishing campaigns. Organizations relying on Seriously Simple Podcasting for their WordPress sites may inadvertently leak API keys, database credentials, or other confidential configuration details. This could lead to unauthorized access to backend systems or data exfiltration. The impact is heightened in sectors with strict data protection regulations like GDPR, where data leakage can result in legal penalties and reputational damage. Additionally, the vulnerability could undermine trust in digital content platforms and disrupt podcast distribution channels. Given the plugin's popularity, a wide range of small to medium enterprises and individual content creators across Europe could be affected, amplifying the overall risk landscape.

1. Monitor official channels for the release of a security patch for Seriously Simple Podcasting and apply updates immediately upon availability. 2. In the interim, restrict access to WordPress admin areas and plugin-related endpoints using web application firewalls (WAFs) or IP whitelisting to limit exposure. 3. Conduct an audit of sensitive data embedded within the plugin or site configurations and remove or secure any exposed credentials or keys. 4. Implement strict access controls and least privilege principles for users managing the WordPress site. 5. Enable logging and monitoring to detect unusual access patterns or attempts to retrieve sensitive data. 6. Consider isolating podcasting services or migrating to alternative plugins with a stronger security track record if immediate patching is not feasible. 7. Educate site administrators about the risks and encourage regular security reviews of WordPress plugins and themes.
