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

**Signal:** High exploit likelihood. EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 71.7% , percentile 99: FIRST’s model estimates a 71.7% chance of exploitation activity in the next 30 days, higher than 99% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes org.xwiki.contrib.changerequest:application-changerequest-ui (Maven) >= 0.11, < 1.9.2, fixed in 1.9.2 . Check your lockfile, including transitive dependencies.

## What it is

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.

## Affected packages

- Maven `org.xwiki.contrib.changerequest:application-changerequest-ui` >= 0.11, < 1.9.2 → fixed: 1.9.2

## Affected products (CVE record)

- xwiki-contrib application-changerequest: >= 0.11, < 1.9.2

- GitHub CVSS 3.1: 10.0 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 71.74% probability of exploitation activity in the next 30 days; percentile 99.
