CVE-2025-53340 is a Missing Authorization vulnerability (CWE-862) identified in the Awesome Support plugin developed by awesomesupport, affecting versions up to and including 6.3.4. This vulnerability arises when the application fails to properly enforce authorization checks, allowing unauthenticated remote attackers to access certain resources or functionalities that should be restricted. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N), the vulnerability can be exploited remotely over the network without any privileges or user interaction, and it results in limited confidentiality impact without affecting integrity or availability. Specifically, an attacker could potentially access some sensitive information or data that should be protected, but cannot modify or disrupt the system. No known exploits are currently reported in the wild, and no patches or fixes have been linked yet. The vulnerability was reserved in June 2025 and published in September 2025, indicating it is a recent discovery. The absence of a patch link suggests that users of Awesome Support should be vigilant for forthcoming updates or mitigations. Awesome Support is a widely used WordPress helpdesk and support ticketing plugin, often deployed by organizations to manage customer support workflows. The missing authorization flaw could allow attackers to bypass access controls, potentially exposing customer data or internal support tickets that contain sensitive information.

For European organizations using the Awesome Support plugin, this vulnerability poses a risk to the confidentiality of customer and internal support data. Although the impact is limited to confidentiality and does not affect integrity or availability, unauthorized data exposure can lead to privacy violations under GDPR and damage customer trust. Organizations in sectors with strict data protection requirements, such as finance, healthcare, and public services, may face regulatory penalties if sensitive personal data is exposed. Since the vulnerability requires no authentication or user interaction, it can be exploited remotely by attackers scanning for vulnerable instances, increasing the risk of widespread data leakage. The lack of known exploits in the wild currently reduces immediate risk, but the ease of exploitation and the plugin’s popularity mean that attackers may develop exploits soon. European organizations relying on Awesome Support for customer service should consider this vulnerability a medium risk that warrants prompt attention to prevent data breaches and compliance issues.

1. Monitor the official Awesome Support plugin channels and vendor announcements closely for patches or security updates addressing CVE-2025-53340 and apply them immediately upon release. 2. Until a patch is available, restrict access to the WordPress admin and plugin endpoints by implementing IP whitelisting or VPN access controls to limit exposure to trusted users only. 3. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting Awesome Support plugin endpoints that could exploit missing authorization. 4. Conduct an internal audit of the data accessible via the plugin to identify sensitive information that could be exposed and apply additional encryption or access controls at the application or database level. 5. Review and tighten WordPress user roles and permissions to minimize the risk of privilege escalation or unauthorized access through other means. 6. Implement comprehensive logging and monitoring to detect unusual access patterns or data exfiltration attempts related to the plugin. 7. Educate IT and security teams about this vulnerability to ensure rapid response and incident handling if exploitation attempts are detected.
