The vulnerability identified as CVE-2025-66110 affects the bPlugins Tiktok Feed plugin for WordPress, specifically versions up to and including 1.0.22. The core issue is a missing authorization check, meaning that certain actions or data access points within the plugin do not properly verify whether the requester has the necessary permissions. This misconfiguration leads to an incorrect access control security level, allowing an attacker to perform unauthorized operations. Since the plugin integrates TikTok feeds into WordPress sites, exploitation could allow attackers to manipulate feed content, access sensitive configuration data, or potentially inject malicious content that could affect site visitors. The vulnerability does not require user interaction, and while no known exploits are currently reported in the wild, the risk remains significant due to the nature of missing authorization flaws. The absence of a CVSS score indicates that the vulnerability is newly published and not yet fully assessed, but the technical details suggest a serious security gap. The plugin is commonly used in WordPress environments to display TikTok content, which means a broad range of websites could be affected, especially those relying on social media integration for marketing or content delivery.

For European organizations, this vulnerability could lead to unauthorized access to website content management features or data exposed via the TikTok Feed plugin. This could result in data confidentiality breaches if sensitive configuration or user data is accessible, integrity issues if attackers modify displayed content or inject malicious code, and reputational damage if the website is compromised. E-commerce sites, media outlets, and marketing agencies using this plugin are particularly at risk, as unauthorized content manipulation could mislead customers or damage brand trust. Additionally, compromised sites could be used as vectors for further attacks, including phishing or malware distribution. The lack of current exploits reduces immediate risk but does not eliminate the threat, especially as attackers often develop exploits rapidly after vulnerability disclosure. The impact is heightened in sectors where social media integration is critical for customer engagement and brand presence.

Organizations should immediately audit their WordPress installations to identify the presence of the bPlugins Tiktok Feed plugin, especially versions up to 1.0.22. If found, they should disable or remove the plugin until a security patch is released. In the absence of an official patch, applying strict web application firewall (WAF) rules to restrict unauthorized access to plugin endpoints can help mitigate exploitation. Administrators should review and tighten access control configurations on their WordPress sites, ensuring that only authenticated and authorized users can access plugin functionalities. Monitoring website logs for unusual access patterns related to the plugin's endpoints can provide early detection of exploitation attempts. Additionally, organizations should maintain regular backups of their websites to enable quick recovery in case of compromise. Engaging with the plugin vendor or security community for updates and patches is also recommended.
