CRITICAL 9.8REMOTEDOWNGRADE

CVE-2020-24030 is a critical-severity flaw (CVSS 9.8) affecting qualiex. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

ForLogic Qualiex v1 and v3 has weak token expiration. This allows remote unauthenticated privilege escalation and access to sensitive data via token reuse. NOTE: as of 2025-10-14, the Supplier's perspective is that this is "not exploitable in the current implementation. Tokens are properly expired, invalidated, and bound to session context. Attempts to alter the token payload to extend its validity do not affect server-side validation."

Why this priority

Critical severity
Remotely exploitable, no login, no user action
