About the vulnerability

Critical Vulnerabilities

Threats posed by the vulnerabilities

CVE-2026-71362 – Adobe Commerce Incorrect Authorization

By exploiting the vulnerability, an unauthenticated attacker can bypass expected authorization controls and perform privileged operations within the affected Commerce environment.

CVE-2026-48413 – Adobe Commerce Stored Cross-Site Scripting

Allows malicious script content to be stored and subsequently executed in the context of affected users, potentially resulting in arbitrary code execution.

CVE-2026-48414 – Adobe Commerce Stored Cross-Site Scripting

An attacker with the required privileges could exploit the stored XSS condition to execute malicious content in a victim’s browser context, potentially leading to further compromise.

By exploiting these vulnerabilities, an attacker can:

• Escalate privileges within affected Adobe Commerce environments.
• Execute arbitrary code through exploitation of stored XSS vulnerabilities.
• Bypass authorization and security controls.
• Access protected application functionality without appropriate authorization.
• Manipulate sensitive Commerce application data.
• Potentially access sensitive customer or business information.
• Compromise vulnerable Adobe Commerce applications.
• Disrupt business-critical Commerce services.
• Use compromised Commerce infrastructure as a foothold for further attacks.

Official mitigation guide

Organizations should:

• Apply the applicable August 2026 Adobe Commerce security updates as soon as operationally feasible.
• Prioritize CVE-2026-71362 because of its critical severity, unauthenticated attack path, and potential for privilege escalation.
• Review Adobe’s official APSB26-92 bulletin to identify affected products and applicable security updates.
• Upgrade affected Adobe Commerce installations to the corresponding August 2026 security release.
• Upgrade Adobe Commerce B2B installations to the corresponding August 2026 release where applicable.
• Upgrade Magento Open-Source installations to the corresponding August 2026 security release.
• Verify successful patch deployment through the organization’s patch-management process.
• Where immediate patching is not possible, restrict exposure of administrative and sensitive Commerce functionality and strengthen monitoring until remediation is completed.
