CVE-2026-15967Network attack vector

Account-policy bypass via stale refresh tokens

Published Jul 23, 2026 · Updated Jul 23, 2026

Insufficient session expiration in MOVEit Transfer before 2025.1.5 and 2026.0.0 through 2026.0.2 allows remote attackers to retain REST API access. REST API token refresh checks fail to enforce current account access policies, allowing a previously issued refresh token to remain effective after account restrictions change. Exploitation requires user interaction; Progress has not disclosed which policy changes are bypassed or the exact data and actions exposed.
