# CVE-2024-55879: XWiki allows RCE from script right in configurable sections

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (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 1.1% , percentile 64: FIRST’s model estimates a 1.1% chance of exploitation activity in the next 30 days, higher than 64% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs an account (high (admin)). Exposure depends on who can log in.
- Only applies if your dependency tree includes org.xwiki.platform:xwiki-platform-administration-ui (Maven) >= 2.3, < 15.10.9, fixed in 15.10.9 ; org.xwiki.platform:xwiki-platform-administration-ui (Maven) >= 16.0.0-rc-1, < 16.3.0, fixed in 16.3.0 . Check your lockfile, including transitive dependencies.

## What it is

XWiki Platform is a generic wiki platform. Starting in version 2.3 and prior to versions 15.10.9, 16.3.0, any user with script rights can perform arbitrary remote code execution by adding instances of XWiki.ConfigurableClass to any page. This compromises the confidentiality, integrity and availability of the whole XWiki installation. This has been patched in XWiki 15.10.9 and 16.3.0. No known workarounds are available except upgrading.

## Affected packages

- Maven `org.xwiki.platform:xwiki-platform-administration-ui` >= 2.3, < 15.10.9 → fixed: 15.10.9
- Maven `org.xwiki.platform:xwiki-platform-administration-ui` >= 16.0.0-rc-1, < 16.3.0 → fixed: 16.3.0

## Affected products (CVE record)

- xwiki xwiki-platform: >= 2.3, < 15.10.9, >= 16.0.0-rc-1, < 16.3.0

## Severity

- GitHub_M CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:H/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): 1.07% probability of exploitation activity in the next 30 days; percentile 64.
