CVE-2025-27188 is an Improper Authorization vulnerability (CWE-863) affecting multiple versions of Adobe Commerce, specifically versions 2.4.4-p12 through 2.4.8-beta2 and earlier. Adobe Commerce is a widely used e-commerce platform that enables businesses to manage online storefronts. This vulnerability allows an attacker with some level of privileges (low privileges) to escalate their privileges by bypassing authorization controls. The flaw lies in the incorrect enforcement of authorization checks, which means that certain operations or resources that should be restricted to higher-privileged users can be accessed or manipulated by users with lesser privileges. Notably, exploitation does not require any user interaction, and the attack vector is network-based (AV:N), meaning an attacker can exploit this remotely over the network. The CVSS 3.1 base score is 4.3, indicating a medium severity level. The impact primarily affects integrity, as unauthorized privilege escalation can lead to unauthorized changes or administrative actions within the Adobe Commerce environment. Confidentiality and availability impacts are not indicated. No known exploits are currently reported in the wild, and no patches or mitigations have been linked yet. The vulnerability requires the attacker to have some level of privileges (PR:L), so it is not exploitable by unauthenticated external actors but rather by authenticated users with limited access. The scope remains unchanged (S:U), meaning the vulnerability affects only the vulnerable component without impacting other components or systems. Given Adobe Commerce's role in managing sensitive business and customer data, unauthorized privilege escalation could allow attackers to manipulate product listings, pricing, order processing, or customer information, potentially leading to fraud, data tampering, or disruption of business operations.

For European organizations using Adobe Commerce, this vulnerability poses a risk of unauthorized privilege escalation within their e-commerce platforms. Attackers who gain low-level access—such as through compromised employee credentials or weak account management—could exploit this flaw to gain administrative privileges. This could lead to unauthorized modification of product catalogs, pricing, order fulfillment processes, or customer data, undermining data integrity and potentially causing financial losses or reputational damage. Given the critical role of e-commerce in retail and B2B sectors across Europe, exploitation could disrupt business continuity and customer trust. Additionally, unauthorized access could facilitate fraudulent transactions or data leakage if combined with other vulnerabilities or misconfigurations. While the vulnerability does not directly impact confidentiality or availability, the integrity compromise can have cascading effects on business operations and compliance with data protection regulations such as GDPR. Organizations in sectors with high e-commerce reliance, including retail, manufacturing, and wholesale distribution, are particularly at risk.

Implement strict access control policies and regularly audit user privileges to ensure that only necessary permissions are granted, minimizing the risk of low-privilege accounts being exploited. Monitor and analyze logs for unusual privilege escalation attempts or unauthorized administrative actions within Adobe Commerce environments. Apply the latest security updates and patches from Adobe as soon as they become available, even though no patch links are currently provided, maintain close monitoring of Adobe security advisories. Enforce multi-factor authentication (MFA) for all users with access to Adobe Commerce to reduce the risk of credential compromise leading to exploitation. Segment the Adobe Commerce environment within the network to limit exposure and restrict access to trusted IP addresses and networks only. Conduct regular security assessments and penetration testing focused on authorization controls within Adobe Commerce to detect and remediate similar weaknesses proactively. Educate administrators and users about the risks of privilege escalation and encourage prompt reporting of suspicious activities. Implement web application firewalls (WAF) with custom rules to detect and block anomalous requests that may attempt to exploit authorization flaws.
