MOVEit Transfer: Authentication Bypass by Spoofing
CVE-2026-8651 is a high-severity authentication bypass by spoofing vulnerability in MOVEit Transfer from Progress Software, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 2025.1.3, 2025.0.7 as the first without the flaw, so updating MOVEit Transfer to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.37% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update MOVEit Transfer to 2025.1.3 or 2025.0.7, whichever matches your release line, or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
