GoAnywhere MFT: Relative Path Traversal
CVE-2026-15913 is a high-severity relative path traversal vulnerability in GoAnywhere MFT from Fortra, with a CVSS 3.1 base score of 7.7 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists version 7.10.2 as the first without the flaw, so updating GoAnywhere MFT to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.44% 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 GoAnywhere MFT to 7.10.2 or a later version.
- Read the advisory on fortra.com for workarounds and exact fixed builds.

The underlying weakness: Relative Path Traversal
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as.. that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
