DescriptionCVE.org
Adobe Commerce versions 2.4.9-alpha3, 2.4.8-p3, 2.4.7-p8, 2.4.6-p13, 2.4.5-p15, 2.4.4-p16 and earlier are affected by an Incorrect Authorization vulnerability that could result in a Security feature bypass. An attacker could leverage this vulnerability to bypass security measures and gain unauthorized view access of data. Exploitation of this issue does not require user interaction.
Executive ViewAI
Adobe Commerce installations running versions 2.4.9-alpha3 through 2.4.4-p16 are vulnerable to an authorization bypass that could allow attackers to circumvent security controls and access restricted functionality. Organizations using affected Commerce versions face immediate risk of unauthorized access to sensitive commerce operations until patches become available.
Implement Web Application Firewall (WAF) rules to detect and block authorization bypass attempts; restrict administrative console access to whitelisted IP ranges and VPNs; disable non-critical commerce features temporarily if feasible; enforce multi-factor authentication on all admin accounts; increase monitoring and logging of authorization-related events; consider running affected systems in restricted mode until patches available.
