# BMC ITSM SmartIT: stored XSS lets logged-in users run scripts

BMC IT Service Management Suite's SmartIT attachment feature does not neutralize uploaded script content, so a stored cross-site scripting flaw exists. An authenticated user can make script run in other users' browsers.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Confirm whether BMC IT Service Management Suite with SmartIT is deployed and which version runs, against versions 25.3.01, 25.4.01 and 26.1.01.

## Fix

- Versions 25.3.01, 25.4.01 and 26.1.01 are listed as affected; the sources do not name a fixed version.

## Timeline

- 2026-10-29T13:25:07+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-113690

## From the sources

Stored cross-site scripting in the SmartIT attachment feature of BMC IT Service Management Suite versions 25.3.01, 25.4.01, and 26.1.01 allows authenticated users to execute uploaded script content in other users' browsers.
