CERT Polska coordinated disclosure of CVE-2026-41874, a vulnerability in OpenSolution Quick.Cart e-commerce software. The flaw stems from hard-coded, plaintext admin credentials stored in a configuration file, which could be retrieved by an attacker who already has access to the server's file system, enabling privilege escalation to administrative access.
Only version 6.7 was tested, but CERT Polska notes that all versions of the product should be considered affected. The vendor assessed the likelihood of exploitation as very low and has decided not to release a fix, meaning the vulnerability will likely remain unpatched. Organizations running Quick.Cart should review file system access controls and consider the credential exposure risk when hardening their deployments, since no vendor remediation is expected.
