CVE-2025-49559 is a path traversal vulnerability (CWE-22) identified in Adobe Commerce versions 2.4.9-alpha1, 2.4.8-p1, 2.4.7-p6, 2.4.6-p11, 2.4.5-p13, 2.4.4-p14, and earlier. The vulnerability arises due to improper validation and limitation of pathname inputs, allowing an attacker to traverse directories beyond the intended restricted directory boundaries. This flaw enables unauthorized modification of limited data, effectively bypassing security features designed to protect sensitive files or configuration data. The vulnerability can be exploited remotely without any authentication or user interaction, increasing its risk profile. The CVSS v3.1 base score is 5.3, reflecting medium severity, with an attack vector of network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), no confidentiality impact (C:N), limited integrity impact (I:L), and no availability impact (A:N). Although no known exploits are currently reported in the wild, the vulnerability's nature makes it a candidate for potential exploitation, especially in environments where Adobe Commerce is exposed to the internet. The lack of available patches at the time of reporting necessitates proactive mitigation. This vulnerability threatens the integrity of data managed by Adobe Commerce platforms, potentially allowing attackers to alter critical e-commerce data, configurations, or files, which could lead to further compromise or disruption of services.

The primary impact of CVE-2025-49559 is on the integrity of data within Adobe Commerce installations. Successful exploitation allows attackers to modify restricted data, which could include configuration files, product information, pricing, or transactional data. This could lead to fraudulent transactions, unauthorized price changes, or manipulation of customer data. Although confidentiality and availability are not directly impacted, the integrity breach can undermine trust in the e-commerce platform and lead to financial losses or reputational damage. Given that exploitation requires no authentication or user interaction, attackers can remotely target vulnerable systems at scale. Organizations relying on Adobe Commerce for their online storefronts face risks of data tampering, potential compliance violations, and downstream impacts on business operations. The medium CVSS score reflects a moderate but actionable threat that should be addressed promptly to prevent escalation or chained attacks.

1. Apply official patches from Adobe immediately once they become available for the affected versions of Adobe Commerce. 2. Until patches are released, implement strict input validation and sanitization on all user-supplied pathname inputs to prevent directory traversal sequences such as '../'. 3. Employ web application firewalls (WAFs) with rules specifically designed to detect and block path traversal attempts targeting Adobe Commerce endpoints. 4. Restrict file system permissions for the web server process to limit the scope of accessible directories and files, minimizing potential damage from traversal exploits. 5. Monitor logs for unusual access patterns or attempts to access restricted directories and files, enabling early detection of exploitation attempts. 6. Conduct regular security assessments and code reviews focusing on input handling and path validation in custom extensions or plugins integrated with Adobe Commerce. 7. Educate development and operations teams about the risks of path traversal vulnerabilities and secure coding practices to prevent similar issues in the future.
