Progress MOVEit Transfer: Insufficient session expiration
Summary
Progress MOVEit Transfer contains an insufficient session expiration flaw (CWE-613), tracked as CVE-2026-89073. The vendor describes it as a way to bypass access restrictions, and an attacker may be able to reuse sessions that should have expired. The vendor bulletin rates it CVSS 7.5 (High), and CISA's SSVC assessment reports total technical impact. The CVSS 9.8 in the submitted data could not be confirmed, so the vendor score is used here and the live NVD score should be checked.
