CVE-2025-54710 is a Missing Authorization vulnerability (CWE-862) identified in the bPlugins Tiktok Feed plugin, affecting versions up to 1.0.21. This vulnerability arises because certain functionalities within the plugin are not properly constrained by Access Control Lists (ACLs), allowing users with limited privileges (requiring only low-level privileges, PR:L) to access or invoke functions that should be restricted. The vulnerability does not require user interaction (UI:N) and can be exploited remotely over the network (AV:N) with low attack complexity (AC:L). The scope of the vulnerability is unchanged (S:U), meaning the impact is limited to the vulnerable component itself. The CVSS v3.1 base score is 7.1, indicating a high severity level. The impact primarily affects integrity and availability, with no direct confidentiality impact. Specifically, attackers can manipulate or disrupt the plugin's functionality, potentially leading to data integrity issues or denial of service conditions. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability was published on August 28, 2025, and was reserved a month earlier, indicating recent discovery and disclosure. The bPlugins Tiktok Feed plugin is typically used to integrate TikTok content feeds into websites, often WordPress-based, which means the vulnerability could affect websites relying on this plugin for social media content display. Given the missing authorization, attackers with some level of authenticated access could escalate their privileges or perform unauthorized actions within the plugin's scope.

For European organizations, the impact of CVE-2025-54710 can be significant, especially for those relying on WordPress sites or other CMS platforms that use the bPlugins Tiktok Feed plugin to display TikTok content. The unauthorized access to plugin functionality could allow attackers to alter displayed content, inject malicious scripts, or disrupt service availability, potentially damaging brand reputation and user trust. Organizations in sectors such as media, marketing, e-commerce, and public services that actively engage audiences via social media integrations are particularly at risk. Additionally, the integrity compromise could lead to misinformation or unauthorized content dissemination, which may have regulatory and compliance implications under GDPR if personal data or user interactions are affected. The availability impact could result in service disruptions, affecting customer experience and operational continuity. Since exploitation requires low privileges but no user interaction, insider threats or compromised low-level accounts could be leveraged to exploit this vulnerability, increasing the risk profile for organizations with large user bases or multiple administrators.

To mitigate CVE-2025-54710, European organizations should first identify all instances of the bPlugins Tiktok Feed plugin in their environments and assess their version. Immediate steps include restricting access to the plugin's administrative and functional interfaces to trusted users only, implementing strict role-based access controls (RBAC) to limit privileges to the minimum necessary. Monitoring and logging access to the plugin's functionalities should be enhanced to detect any anomalous or unauthorized usage patterns. Since no official patches are currently linked, organizations should follow closely for vendor updates or security advisories and apply patches promptly once available. As a temporary workaround, disabling or removing the plugin until a fix is released can prevent exploitation. Additionally, web application firewalls (WAFs) can be configured to block suspicious requests targeting the plugin's endpoints. Conducting regular security audits and penetration testing focusing on plugin vulnerabilities will help identify and remediate similar issues proactively. Finally, educating administrators and users about the risks of privilege misuse and enforcing strong authentication mechanisms will reduce the likelihood of exploitation.
