# CVE-2023-45136: XWiki Platform web templates vulnerable to reflected XSS in the create document form if name validation is enabled

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 5.1% , percentile 92: FIRST’s model estimates a 5.1% chance of exploitation activity in the next 30 days, higher than 92% of all scored CVEs (elevated). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.
- Only applies if your dependency tree includes org.xwiki.platform:xwiki-platform-web-templates (Maven) >= 12.0-rc-1, < 14.10.12, fixed in 14.10.12 ; org.xwiki.platform:xwiki-platform-web-templates (Maven) >= 15.0-rc-1, < 15.5-rc-1, fixed in 15.5-rc-1 . Check your lockfile, including transitive dependencies.

## What it is

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. When document names are validated according to a name strategy (disabled by default), XWiki starting in version 12.0-rc-1 and prior to versions 12.10.12 and 15.5-rc-1 is vulnerable to a reflected cross-site scripting attack in the page creation form. This allows an attacker to execute arbitrary actions with the rights of the user opening the malicious link. Depending on the rights of the user, this may allow remote code execution and full read and write access to the whole XWiki installation. This has been patched in XWiki 14.10.12 and 15.5-rc-1 by adding appropriate escaping. The vulnerable template file createinline.vm is part of XWiki's WAR and can be patched by manually applying the changes from the fix.

## Affected packages

- Maven `org.xwiki.platform:xwiki-platform-web-templates` >= 12.0-rc-1, < 14.10.12 → fixed: 14.10.12
- Maven `org.xwiki.platform:xwiki-platform-web-templates` >= 15.0-rc-1, < 15.5-rc-1 → fixed: 15.5-rc-1

## Affected products (CVE record)

- xwiki xwiki-platform: >= 12.0-rc-1, < 14.10.12, >= 15.0-rc-1, < 15.5-rc-1

## Severity

- GitHub_M CVSS 3.1: 9.7 `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.6 `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/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 poc , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 5.12% probability of exploitation activity in the next 30 days; percentile 92.
