CVE-2025-67419 is a Denial of Service vulnerability identified in evershop version 2.1.0 and earlier. The vulnerability is triggered via the GET /images API endpoint, which processes SVG files. The root cause lies in the application’s failure to impose limits on the height of the use-element shadow tree and the dimensions of pattern tiles within SVG files. Attackers can craft malicious SVGs that cause the server to consume excessive CPU and memory resources during rendering or processing, leading to unbounded resource consumption. This results in the exhaustion of server resources, causing the application to become unresponsive or crash, effectively denying service to legitimate users. The attack requires no authentication or user interaction, making it easily exploitable remotely. The CVSS v3.1 score of 7.5 reflects a high severity due to network attack vector, low attack complexity, no privileges required, and no user interaction needed. The vulnerability is classified under CWE-1050, which relates to resource exhaustion issues. No patches or fixes have been officially released yet, and no known exploits have been observed in the wild. However, the potential for disruption is significant, especially for organizations relying on evershop for their e-commerce operations.

For European organizations, this vulnerability poses a substantial risk of service disruption, particularly for those operating e-commerce platforms using evershop 2.1.0 or earlier. A successful exploitation can lead to denial of service, causing downtime, loss of customer trust, and potential revenue loss. The unavailability of the platform can also impact supply chains and customer support services. Since the attack does not require authentication or user interaction, it can be launched by any remote attacker, increasing the threat surface. The impact on confidentiality and integrity is minimal, but availability is severely affected. Organizations in sectors with high reliance on online sales and digital presence, such as retail and logistics, are particularly vulnerable. Additionally, repeated or sustained attacks could strain IT resources and increase operational costs due to incident response and recovery efforts.

To mitigate this vulnerability, organizations should prioritize upgrading to a patched version of evershop once available. In the absence of an official patch, implement strict input validation and sanitization on SVG files uploaded or processed by the application, specifically limiting the height of use-element shadow trees and the dimensions of pattern tiles. Employ web application firewalls (WAFs) to detect and block suspicious SVG payloads or abnormal API request patterns targeting the GET /images endpoint. Rate limiting and request throttling on the API can reduce the risk of resource exhaustion. Monitoring server resource usage and setting alerts for unusual spikes can enable early detection of exploitation attempts. Additionally, consider isolating the SVG processing component in a sandboxed environment to contain resource consumption. Regularly review and update incident response plans to handle potential DoS attacks effectively.
