# IBM Concert: crafted input lets remote attackers run OS commands

Link for people: https://infrastack.ai/live/CVE-2026-6715 (this .md is for agents)

IBM Concert versions 1.0 through 3.0.1.1 pass attacker-supplied input into operating system commands without proper validation. A remote attacker can run arbitrary commands on the server with the privileges of the affected service.

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

## How to check

- Check the IBM Concert version in the installed deployment against the affected range `1.0` through `3.0.1.1`

## Fix

- Fixed version: unknown

## Timeline

- 2026-11-08T19:22:34+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-6715

## From the sources

IBM Concert 1.0 through 3.0.1.1 allows an attacker can supply crafted input that is incorporated into an operating system command without adequate validation or sanitization. Successful exploitation allows remote attackers to execute arbitrary commands on the underlying operating system with the privileges of the affected service.
