CVE-2025-66110 identifies a missing authorization vulnerability in the bPlugins Tiktok Feed WordPress plugin, specifically versions up to and including 1.0.22. The vulnerability arises from incorrectly configured access control security levels, allowing unauthenticated attackers to access plugin functionalities or data that should be restricted. The vulnerability is remotely exploitable over the network without requiring any privileges or user interaction, as indicated by the CVSS vector AV:N/AC:L/PR:N/UI:N. The impact is limited to confidentiality, with no direct effect on integrity or availability. This means attackers could potentially retrieve sensitive information exposed by the plugin but cannot modify data or disrupt service. The plugin integrates TikTok feeds into websites, so the exposed data might include feed content or related metadata. No patches or fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. The vulnerability was published on November 21, 2025, and assigned a medium severity rating with a CVSS score of 5.3. The lack of authorization checks suggests a design or implementation flaw in the plugin's access control mechanisms, which should be addressed by the vendor. Organizations using this plugin should be aware of the risk of unauthorized data exposure and prepare to apply vendor patches or implement compensating controls.

For European organizations, this vulnerability poses a risk of unauthorized disclosure of information embedded in the TikTok Feed plugin on their websites. While it does not allow attackers to alter data or disrupt services, the exposure of feed content or related metadata could lead to privacy concerns, reputational damage, or leakage of sensitive business information. Organizations relying on this plugin for social media integration may inadvertently expose user or organizational data to attackers. This risk is particularly relevant for sectors with strict data protection regulations such as GDPR, where unauthorized data exposure can result in compliance violations and fines. Additionally, attackers could leverage the exposed information for further targeted attacks or social engineering. The medium severity indicates a moderate risk that should be addressed promptly to prevent exploitation, especially in environments where the plugin is publicly accessible. The absence of known exploits reduces immediate urgency but does not eliminate the threat, as attackers may develop exploits in the future.

1. Monitor the bPlugins vendor channels for official patches addressing CVE-2025-66110 and apply them promptly once released. 2. Until patches are available, restrict access to the plugin’s endpoints by implementing web application firewall (WAF) rules that limit access to trusted IPs or authenticated users only. 3. Review and harden WordPress user roles and permissions to minimize exposure of plugin functionalities. 4. Conduct regular security audits and penetration tests focusing on access control mechanisms in all third-party plugins. 5. Implement network segmentation and monitoring to detect unusual access patterns targeting the TikTok Feed plugin endpoints. 6. Disable or remove the plugin if it is not essential to reduce the attack surface. 7. Educate website administrators about the risks of missing authorization and the importance of timely updates and access control configurations. 8. Use security plugins that can enforce additional authorization checks or provide virtual patching capabilities until an official fix is available.
