CVE-2025-54694 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the bPlugins Button Block plugin, affecting versions up to 1.2.0. CSRF vulnerabilities occur when an attacker tricks an authenticated user into submitting a forged request to a web application without their consent, potentially causing unintended actions on behalf of the user. In this case, the Button Block plugin does not adequately verify the origin or intent of requests, allowing attackers to craft malicious web pages or links that, when visited by an authenticated user, can trigger unauthorized state-changing operations within the plugin's functionality. The vulnerability has a CVSS 3.1 base score of 4.3, indicating a medium severity level. The vector details (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N) show that the attack can be performed remotely over the network with low attack complexity, requires no privileges, but does require user interaction (such as clicking a link). The impact is limited to integrity, with no confidentiality or availability impact. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is classified under CWE-352, which is a common web application security weakness related to CSRF attacks. Since the Button Block plugin is typically used within content management systems or website builders, exploitation could allow attackers to manipulate button configurations or trigger unintended actions, potentially leading to unauthorized changes in website behavior or content presentation.

For European organizations, the impact of this CSRF vulnerability depends largely on the deployment scale of the bPlugins Button Block plugin within their web infrastructure. Organizations using this plugin on public-facing websites or intranet portals could face unauthorized modifications to button elements, which might be leveraged to mislead users, redirect traffic, or degrade user experience. While the vulnerability does not directly compromise data confidentiality or availability, the integrity impact could facilitate further social engineering or phishing attacks by altering website navigation or call-to-action elements. This could erode user trust and potentially cause reputational damage, especially for sectors like e-commerce, government services, or financial institutions that rely heavily on web presence. Additionally, if attackers chain this vulnerability with other weaknesses, it could escalate to more severe compromises. The requirement for user interaction limits the attack scope, but targeted phishing campaigns could increase risk. Given the medium severity and absence of known exploits, the immediate threat level is moderate but warrants proactive mitigation to prevent exploitation.

European organizations should implement specific mitigations beyond generic advice to address this CSRF vulnerability effectively. First, ensure that the bPlugins Button Block plugin is updated to a patched version once available; monitor vendor announcements closely. In the interim, apply web application firewall (WAF) rules to detect and block suspicious CSRF-like requests targeting the plugin's endpoints. Implement strict SameSite cookie attributes (preferably 'Strict' or 'Lax') to reduce the risk of cross-origin requests being accepted by browsers. Enforce anti-CSRF tokens in all state-changing requests related to the plugin, verifying token validity server-side. Conduct thorough audits of user roles and permissions to minimize the number of users with privileges that could be abused via CSRF. Educate users about phishing risks and encourage cautious behavior when clicking links from untrusted sources. Additionally, review Content Security Policy (CSP) settings to restrict the domains that can interact with the web application, limiting exposure to malicious external sites. Finally, consider isolating the plugin's functionality or disabling it temporarily if it is not critical, until a secure patch is applied.
