MOVEit Automation: Memory Allocation with Excessive Size Value
CVE-2026-8485 is a high-severity memory allocation with excessive size value vulnerability in MOVEit Automation 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 2025.0.11, 2025.1.7 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 0.35% 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 Automation to 2025.0.11 or 2025.1.7, whichever matches your release line, or a later version.
- Read the advisory on docs.progress.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Uncontrolled Memory Allocation vulnerability in Progress Software MOVEit Automation allows Excessive Allocation. This issue affects MOVEit Automation: before 2025.0.11, from 2025.1.0 before 2025.1.7.

The underlying weakness: Memory Allocation with Excessive Size Value
The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated.
How developers prevent this class of flaw
- Perform adequate input validation against any value that influences the amount of memory that is allocated. Define an appropriate strategy for handling requests that exceed the limit, and consider supporting a configuration option so that the administrator can extend the amount of memory to be used if necessary.
- Run your program using system-provided resource limits for memory. This might still cause the program to crash or exit, but the impact to the rest of the system will be minimized.
