# CVE-2024-21650: XWiki Remote Code Execution Vulnerability via User Registration

**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?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 93.5% , percentile 99.8: FIRST’s model estimates a 93.5% chance of exploitation activity in the next 30 days, higher than 99.8% 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.platform:xwiki-platform-administration-ui (Maven) >= 2.2, < 14.10.17, fixed in 14.10.17 ; org.xwiki.platform:xwiki-platform-administration-ui (Maven) >= 15.0-rc-1, < 15.5.3, fixed in 15.5.3 ; org.xwiki.platform:xwiki-platform-administration-ui (Maven) >= 15.6-rc-1, < 15.8-rc-1, fixed in 15.8-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. XWiki is vulnerable to a remote code execution (RCE) attack through its user registration feature. This issue allows an attacker to execute arbitrary code by crafting malicious payloads in the "first name" or "last name" fields during user registration. This impacts all installations that have user registration enabled for guests. This vulnerability has been patched in XWiki 14.10.17, 15.5.3 and 15.8 RC1.

## Affected packages

- Maven `org.xwiki.platform:xwiki-platform-administration-ui` >= 2.2, < 14.10.17 → fixed: 14.10.17
- Maven `org.xwiki.platform:xwiki-platform-administration-ui` >= 15.0-rc-1, < 15.5.3 → fixed: 15.5.3
- Maven `org.xwiki.platform:xwiki-platform-administration-ui` >= 15.6-rc-1, < 15.8-rc-1 → fixed: 15.8-rc-1

## Affected products (CVE record)

- xwiki xwiki-platform: >= 2.2, < 14.10.17, >= 15.0-rc-1, < 15.5.3, >= 15.6-rc-1, < 15.8-rc-1

## Severity

- GitHub_M CVSS 3.1: 10 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H`
- 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 poc , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 93.48% probability of exploitation activity in the next 30 days; percentile 99.8.
