CVE-2026-48000
Summary
by MITRE • 07/14/2026
Adobe Commerce is affected by an Improper Redirect (Open Redirect) vulnerability that could result in a Security feature bypass. An attacker could construct a malicious URL that redirects a victim to an attacker-controlled site, potentially enabling credential theft and account takeover. Exploitation of this issue requires user interaction in that a victim must click on a malicious link.

Adobe Commerce suffers from an improper redirect vulnerability classified as CWE-601 which allows attackers to manipulate the application's redirection mechanism to point users toward malicious domains. This security flaw exists within the application's URL handling logic where input validation is insufficient to prevent crafted redirect parameters from being processed without proper sanitization or verification. The vulnerability specifically affects the application's security features by enabling attackers to bypass intended access controls and authentication mechanisms through deceptive redirect sequences.
The technical exploitation of this vulnerability occurs when an attacker crafts a malicious URL containing a redirect parameter that points to an external domain controlled by the attacker. When a victim clicks such a link, the Adobe Commerce application processes the redirect parameter without adequate validation, causing the user's browser to navigate away from the legitimate application to the attacker-controlled site. This opens opportunities for credential harvesting through phishing attacks or session hijacking, as users may unknowingly enter their credentials on compromised domains that appear to be legitimate extensions of the Adobe Commerce interface.
The operational impact of this vulnerability extends beyond simple phishing scenarios to encompass broader security feature bypass capabilities within the Adobe Commerce platform. Attackers can leverage this weakness to circumvent intended security controls, potentially gaining unauthorized access to user accounts and sensitive business data. The requirement for user interaction through click-based exploitation means that social engineering becomes a critical component in successful attacks, but the vulnerability itself represents a fundamental flaw in the application's trust model regarding external URL processing.
Organizations should implement comprehensive input validation measures to sanitize all redirect parameters before processing them within the Adobe Commerce application. This includes implementing strict domain whitelisting mechanisms that only permit redirection to known and trusted domains while rejecting any external redirects that do not meet predefined security criteria. Network-level protections such as web application firewalls can provide additional defense-in-depth by monitoring for suspicious redirect patterns and blocking malicious URL constructions. Security patches should be applied immediately upon release from Adobe to address this vulnerability, as the open redirect flaw represents a critical risk when combined with user interaction requirements that enable successful exploitation.
This vulnerability aligns with several ATT&CK techniques including initial access through malicious links and credential access via phishing campaigns. The improper redirect condition creates opportunities for attackers to establish persistent access points within the application ecosystem while potentially bypassing security controls designed to prevent unauthorized redirection. Organizations should conduct thorough security assessments of their Adobe Commerce implementations to identify all potential redirect points and ensure proper validation mechanisms are in place to prevent exploitation.
The remediation approach must address both immediate patching requirements and long-term architectural improvements to prevent similar vulnerabilities from emerging in the application's redirect handling logic. Security teams should implement automated testing procedures that verify redirect parameter handling during regular security assessments, ensuring that all external URL processing adheres to established security protocols. Regular vulnerability scanning and penetration testing should include specific checks for redirect validation weaknesses to maintain ongoing protection against this class of attack vectors.
Organizations utilizing Adobe Commerce must also consider implementing user education programs that raise awareness about suspicious link behavior and the potential dangers of clicking unverified external URLs, particularly in environments where phishing attacks represent significant risk. The combination of technical controls and user awareness creates a more robust defense posture against exploitation of this improper redirect vulnerability while maintaining the application's intended functionality and user experience requirements.
