CVE-2025-66110 identifies a missing authorization vulnerability in the bPlugins Tiktok Feed plugin (versions up to 1.0.22). This plugin integrates TikTok feeds into websites, commonly WordPress-based. The vulnerability arises due to incorrectly configured access control security levels, allowing unauthenticated remote attackers to access or retrieve data that should be restricted. The CVSS 3.1 base score is 5.3, reflecting a medium severity level, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), and no user interaction needed (UI:N). The impact is limited to confidentiality loss (C:L), with no impact on integrity or availability. The vulnerability does not require authentication, making it easier to exploit remotely. Although no exploits are currently known in the wild, the exposure of potentially sensitive data through unauthorized access could lead to information leakage. The plugin's role in embedding TikTok content means that attackers might access user-related or content metadata that could be leveraged for further attacks or privacy violations. The lack of patches at the time of publication necessitates immediate mitigation steps by administrators.

For European organizations, the primary impact is unauthorized disclosure of data accessible via the Tiktok Feed plugin. While the vulnerability does not allow modification or disruption of services, the confidentiality breach could expose user engagement data or internal content feeds, potentially leading to privacy violations or reputational damage. Organizations heavily reliant on social media integrations for marketing or customer engagement may face increased risk of data leakage. Additionally, attackers could use the exposed information as a foothold for more sophisticated attacks such as social engineering or targeted phishing campaigns. The medium severity indicates a moderate risk level, but the ease of exploitation and lack of authentication requirements increase the urgency for mitigation. Compliance with GDPR and other data protection regulations in Europe means that any unauthorized data exposure could result in regulatory scrutiny and fines.

1. Monitor bPlugins official channels for patches addressing CVE-2025-66110 and apply updates promptly once available. 2. Until patches are released, restrict access to the Tiktok Feed plugin endpoints via web application firewall (WAF) rules or server-level access controls to trusted IP addresses only. 3. Implement strict role-based access control (RBAC) on the content management system to limit who can configure or access plugin data. 4. Conduct regular security audits and penetration tests focusing on third-party plugins and their access controls. 5. Disable or remove the Tiktok Feed plugin if it is not essential to reduce attack surface. 6. Employ network segmentation to isolate web-facing services from sensitive internal systems. 7. Monitor web server logs for unusual access patterns targeting the plugin endpoints. 8. Educate website administrators about the risks of unauthorized access and the importance of timely patching.
