CVE-2025-48337 is a security vulnerability classified under CWE-862, which corresponds to Missing Authorization, affecting the QuickcabWP QuickCab plugin up to version 1.3.3. This vulnerability arises when the application fails to properly enforce authorization checks, allowing unauthenticated remote attackers to perform certain actions or access resources that should be restricted. According to the CVSS v3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N), the vulnerability can be exploited remotely over the network without any privileges or user interaction, indicating a low barrier to exploitation. The impact is limited to integrity, meaning attackers can modify data or perform unauthorized actions but cannot directly affect confidentiality or availability. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability affects QuickCab, a WordPress plugin developed by QuickcabWP, which is typically used to manage cab or transportation booking services on WordPress sites. Missing authorization vulnerabilities can lead to unauthorized changes in booking data, pricing, or user information, potentially undermining the trustworthiness and operational integrity of the affected service.

For European organizations, especially those in the transportation, logistics, or local taxi service sectors using WordPress with the QuickCab plugin, this vulnerability poses a moderate risk. Unauthorized modification of booking data or service parameters could disrupt operations, cause financial discrepancies, or damage customer trust. While confidentiality is not directly impacted, integrity violations could lead to fraudulent bookings or manipulated service records. Given the plugin's niche use, the overall impact is limited to organizations relying on this specific software. However, any disruption in transportation services can have cascading effects, especially in urban areas where such services are critical. Additionally, regulatory compliance under GDPR requires maintaining data integrity, so unauthorized modifications could lead to compliance issues if personal data is affected indirectly.

Organizations should immediately verify if they are using the QuickCab plugin version 1.3.3 or earlier and plan to update to a patched version once available. In the absence of an official patch, administrators should implement strict access controls at the WordPress level, including limiting plugin management capabilities to trusted administrators only. Employing Web Application Firewalls (WAFs) to detect and block suspicious requests targeting QuickCab endpoints can reduce exposure. Monitoring logs for unusual activities related to booking modifications or plugin endpoints is critical. Additionally, isolating the WordPress environment and ensuring regular backups of booking data will help in recovery if unauthorized changes occur. Engaging with the plugin vendor or community to obtain timely patches or workarounds is recommended. Lastly, conducting a thorough security review of all plugins and minimizing the attack surface by disabling or removing unused plugins can further reduce risk.
