CVE-2025-53267 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the WordPress plugin "Hide Admin Bar From Front End" developed by Aftab Husain. This vulnerability affects versions up to 1.0.0, allowing an attacker to trick an authenticated user into submitting unwanted requests to the affected application without their consent. Specifically, the CSRF flaw enables an attacker to perform unauthorized actions that alter the plugin's behavior or settings by exploiting the user's active session. The vulnerability is classified under CWE-352, which pertains to CSRF attacks where state-changing requests are not properly protected against forged requests. The CVSS v3.1 base score is 4.3 (medium severity), reflecting that the attack vector is network-based (AV:N), requires no privileges (PR:N), but does require user interaction (UI:R). The impact primarily affects the integrity of the application, as the attacker can induce changes without compromising confidentiality or availability. No known exploits are currently in the wild, and no patches have been linked yet. The plugin is typically used to hide the WordPress admin bar from the front-end interface for certain users, a feature that can be abused if manipulated maliciously. Given the nature of CSRF, the attacker must lure an authenticated user to a malicious site or link to trigger the exploit, which then sends crafted requests to the vulnerable plugin to alter its configuration or behavior without the user's knowledge.

For European organizations using WordPress sites with the "Hide Admin Bar From Front End" plugin, this vulnerability poses a moderate risk. While it does not directly expose sensitive data or cause denial of service, unauthorized changes to plugin settings could lead to a degraded user experience or enable further exploitation by attackers who gain foothold through manipulated configurations. For example, hiding the admin bar improperly might obscure administrative controls or security indicators, potentially facilitating privilege escalation or unauthorized access in chained attacks. Organizations in sectors such as e-commerce, government, and media, which rely heavily on WordPress for public-facing websites, could face reputational damage or operational disruptions if attackers exploit this vulnerability. The requirement for user interaction and an authenticated session limits the scope but does not eliminate risk, especially in environments with many users or where phishing attacks are prevalent. Additionally, the lack of a patch at the time of publication means organizations must rely on mitigation strategies until an official fix is released.

To mitigate this CSRF vulnerability, European organizations should implement the following specific measures: 1) Temporarily disable or uninstall the "Hide Admin Bar From Front End" plugin until a security patch is available. 2) If disabling the plugin is not feasible, restrict access to the WordPress admin area and plugin settings to trusted IP addresses or via VPN to reduce exposure. 3) Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious cross-site requests targeting the plugin endpoints. 4) Educate users with administrative privileges about phishing risks and the importance of not clicking on untrusted links while authenticated. 5) Monitor logs for unusual POST requests or changes to plugin configurations that could indicate exploitation attempts. 6) Keep WordPress core and all plugins updated regularly and subscribe to security advisories from the plugin author or trusted vulnerability databases to apply patches promptly once available. 7) Consider implementing anti-CSRF tokens and verifying the presence of nonce values in plugin requests if custom development or overrides are possible.
