# Oracle Siebel CRM Deployment: unauthenticated network flaw exposes critical data

Oracle Siebel CRM Deployment's Server Infrastructure component has a flaw in versions 17.0 through 26.9 that lets an unauthenticated attacker reach it over TLS. A successful attack gives unauthorized read access to critical data held by the deployment.

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

## How to check

- Identify Siebel CRM Deployment installs and their version, for example via the installed Siebel release on the server (unknown exact command in sources)
- Check whether the Siebel server endpoints are reachable from untrusted networks

## Fix

- Apply the Oracle Critical Patch Update that addresses CVE-2026-101460 for the affected Siebel CRM release (exact patch name unknown)
- Move affected versions off `17.0` through `26.9` once a fixed release is available (fixed version unknown)
