Since the vendor has not responded or released a fix, users should monitor official OpenCart channels for updates. Until a patch is available, restrict access to the Extension Installer Page and limit high privilege accounts to trusted users only to reduce risk.
Description
CVE-2026-5331 is a medium severity path traversal vulnerability in OpenCart version 4.1.0.3, specifically in the Extension Installer Page's installer.php file. This vulnerability allows an attacker with high privileges to remotely manipulate file paths, potentially accessing unauthorized files. The vulnerability has been publicly disclosed, but no vendor response or patch is currently available. Exploitation requires high privileges, and the impact is limited by low confidentiality, integrity, and availability requirements. No known exploits are reported in the wild at this time.
