MOVEit Automation: Authentication Bypass by Primary Weakness

Published Updated By the CyberSecBulletin desk

CVE-2026-4670 is a critical-severity authentication bypass by primary weakness vulnerability in MOVEit Automation from Progress Software, with a CVSS 3.1 base score of 9.8 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 2025.0.9, 2024.1.8, 2024.0.0 as the first without the flaw, so updating MOVEit Automation to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 5.04% chance of exploitation within 30 days, which is in the top 7.58% of all scored CVEs.

Critical severity: a successful attack would have severe impact.

What to do

  1. Update MOVEit Automation to 2025.0.9 or 2024.1.8 or 2024.0.0, whichever matches your release line, or a later version.
  2. Read the advisory on community.progress.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
