A critical Path Traversal vulnerability in Adobe Commerce allows an authenticated attacker to access restricted directories, potentially leading to unauthorized data exposure or system compromise.

This vulnerability is a Path Traversal (CWE-22) issue. It requires an attacker to possess high privileges (PR:H) to successfully manipulate pathnames, allowing access to files outside of the intended directory.

With a CVSS score of 8.7, this vulnerability represents a high risk to the platform's security. An attacker could potentially read sensitive configuration files, source code, or internal data, leading to a complete compromise of the application environment.

Immediate Action: Apply the security updates referenced in Adobe's APSB26-49 advisory.

Proactive Monitoring: Review file system access logs for path traversal patterns (e.g., ../ sequences) targeting sensitive system or configuration directories.

Compensating Controls: Ensure the web application process runs with the least privilege necessary to limit the scope of potential file access in the event of an exploit.

Public Exploit Available: Unknown

Administrators must prioritize the application of the latest security patches for Adobe Commerce as outlined in the APSB26-49 advisory. Restricting administrative access to trusted personnel remains a critical defense-in-depth measure against this class of vulnerability.
