CVE-2025-66061 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Seriously Simple Podcasting WordPress plugin developed by Craig Hewitt. The vulnerability affects all versions up to and including 3.13.0. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application, causing the application to perform unintended actions on behalf of the user. In this case, the plugin lacks sufficient anti-CSRF protections, such as nonce verification or token validation, allowing attackers to craft malicious web pages or links that, when visited by an authenticated user, execute unauthorized commands within the podcasting plugin context. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N) indicates that the attack can be performed remotely over the network with low attack complexity, requires no privileges, but does require user interaction. The impact is limited to confidentiality, potentially exposing some user data or settings, but does not affect integrity or availability of the system. No known exploits have been reported in the wild, and no patches or fixes are currently linked, suggesting that users should monitor for updates. This vulnerability is particularly relevant for WordPress sites that use Seriously Simple Podcasting to manage podcast content, as attackers could manipulate podcast settings or user data via CSRF attacks.

For European organizations, the impact of this vulnerability is primarily a risk of unauthorized actions being performed on podcasting management interfaces, potentially leading to exposure of sensitive podcast metadata or user information. While the confidentiality impact is low, unauthorized changes could disrupt podcast content management workflows or expose private data. Organizations relying on Seriously Simple Podcasting for public-facing content may face reputational damage if attackers manipulate podcast feeds or settings. The lack of impact on integrity and availability reduces the risk of system compromise or denial of service. However, given the widespread use of WordPress and the growing popularity of podcasting in Europe, especially among media companies, educational institutions, and marketing agencies, this vulnerability could be leveraged as part of broader social engineering or targeted campaigns. The requirement for user interaction limits large-scale automated exploitation but does not eliminate risk in targeted spear-phishing or malicious web campaigns.

Organizations should prioritize applying security patches as soon as they become available from the plugin vendor. Until patches are released, administrators should implement additional security controls such as enabling Web Application Firewalls (WAFs) with CSRF protection rules to detect and block suspicious requests. Restrict administrative access to the podcasting plugin by limiting user roles and permissions, ensuring only trusted users have the ability to modify podcast settings. Employ security headers like SameSite cookies to reduce CSRF attack surface. Educate users and administrators about the risks of clicking unknown links or visiting untrusted websites while authenticated to WordPress dashboards. Regularly audit plugin versions and monitor security advisories from Craig Hewitt and WordPress security channels. Consider disabling or replacing the plugin if immediate patching is not feasible and the risk is unacceptable.
