Description

CERT Polska has received a report about vulnerabilities in Quick.Cart software and participated in coordination of their disclosure.

The vulnerability CVE-2026-23796: Quick.Cart allows a user's session identifier to be set before authentication. The value of this session ID stays the same after authentication. This behavior enables an attacker to fix a session ID for a victim and later hijack the authenticated session.

The vulnerability CVE-2026-23797: In Quick.Cart user passwords are stored in plaintext form. An attacker with high privileges can display users' password in user editing page.

The vendor was notified early about these vulnerabilities, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.7 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.
