CVE-2026-102367
mall4j through 4.0 contains an insufficient session expiration vulnerability in the token refresh endpoint that fails to validate the enabled flag when issuing new sessions.
Does this matter?
Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.
Description
mall4j through 4.0 contains an insufficient session expiration vulnerability in the token refresh endpoint that fails to validate the enabled flag when issuing new sessions. Disabled user accounts can indefinitely renew their sessions through the POST /token/refresh endpoint, retaining access that account disabling was intended to remove.
