An issue was discovered in Optimizely Configured Commerce before 5.2.2408. A medium-severity session issue exists in the Commerce B2B application, affecting the longevity of active sessions in the storefront. This allows session tokens tied to logged-out sessions to still be active and usable.
According to WASC, “Insufficient Session Expiration is when a web site permits an attacker to reuse old session credentials or session IDs for authorization.”
