CVE-2025-48282 is a medium-severity vulnerability classified under CWE-862, which pertains to Missing Authorization. This vulnerability affects the Majestic Support product, specifically versions up to 1.1.0. The core issue is an incorrect or missing implementation of access control mechanisms, allowing unauthorized users to perform actions or access resources that should be restricted. The CVSS v3.1 base score is 5.3, indicating a moderate risk level. The vector string (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N) reveals that the vulnerability can be exploited remotely over the network without requiring any privileges or user interaction. The impact is limited to integrity, meaning unauthorized modifications or actions can be performed, but confidentiality and availability are not directly affected. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability arises from a failure to enforce proper authorization checks, which could allow attackers to manipulate or alter data or system states within the Majestic Support application. Given the nature of the product—likely a support or ticketing system—such unauthorized actions could lead to data tampering, unauthorized changes to support tickets, or escalation of privileges within the application context.

For European organizations using Majestic Support, this vulnerability poses a risk to the integrity of their support and customer service operations. Unauthorized modifications could lead to incorrect handling of support tickets, data corruption, or manipulation of internal workflows. This could undermine trust in customer support processes and potentially expose organizations to compliance risks, especially under regulations like GDPR, where data integrity and proper access controls are critical. While confidentiality and availability are not directly impacted, the integrity breach could facilitate further attacks or fraud if attackers manipulate support data or processes. Organizations relying heavily on Majestic Support for critical customer interactions or internal issue tracking may face operational disruptions or reputational damage if this vulnerability is exploited.

Given the absence of an official patch, European organizations should implement compensating controls immediately. These include: 1) Restricting network access to the Majestic Support application to trusted IP ranges or VPN-only access to reduce exposure to remote attackers. 2) Implementing additional access control layers at the network or application gateway level, such as web application firewalls (WAFs) with custom rules to detect and block unauthorized requests. 3) Conducting thorough audits of user permissions and roles within Majestic Support to ensure the principle of least privilege is enforced. 4) Monitoring logs and user activities for unusual or unauthorized actions that could indicate exploitation attempts. 5) Preparing incident response plans specific to this vulnerability to quickly contain any detected misuse. Once an official patch is released, organizations should prioritize immediate deployment after testing in their environments.
