CVE-2026-45055: SSRF in CubeCart v6 Ecommerce Software

The primary impact of this SSRF vulnerability lies in the ability of an unauthenticated attacker to manipulate password reset links. By crafting a malicious Host header, an attacker can redirect the password reset link to an attacker-controlled domain. When a user clicks this link, they are prompted to enter a new password on the attacker's site, effectively granting the attacker control of the user's account. This could lead to data theft, fraudulent transactions, or further compromise of the ecommerce platform. The vulnerability's impact is amplified by the fact that it targets a critical function – password recovery – which is often used by legitimate users, increasing the likelihood of exploitation. This attack pattern shares similarities with other SSRF-based phishing campaigns, where attackers leverage trusted domains to trick users into divulging credentials.

The primary mitigation for CVE-2026-45055 is to immediately upgrade CubeCart to version 6.7.2 or later. If upgrading is not immediately feasible, consider implementing a Web Application Firewall (WAF) rule to filter requests with suspicious Host headers. Specifically, block requests where the Host header contains unexpected or malicious domains. Additionally, review CubeCart's configuration to ensure that any custom settings related to email sending are secure and do not introduce similar vulnerabilities. After upgrading, confirm the fix by attempting to trigger a password reset and verifying that the generated link points to the correct CubeCart domain.
