# CVE-2025-23025: XWiki Realtime WYSIWYG Editor extension allows privilege escalation (PR) through realtime WYSIWYG editing

**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?

- 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 0.4% , percentile 35: FIRST’s model estimates a 0.4% chance of exploitation activity in the next 30 days, higher than 35% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs an account (low (any account)). Exposure depends on who can log in.
- Only applies if your dependency tree includes org.xwiki.platform:xwiki-platform-realtime-wysiwyg-ui (Maven) >= 13.9-rc-1, < 15.10.12, fixed in 15.10.12 ; org.xwiki.platform:xwiki-platform-realtime-wysiwyg-ui (Maven) >= 16.0.0-rc-1, < 16.4.1, fixed in 16.4.1 ; org.xwiki.platform:xwiki-platform-realtime-wysiwyg-ui (Maven) >= 16.5.0-rc-1, < 16.6.0-rc-1, fixed in 16.6.0-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. NOTE: The Realtime WYSIWYG Editor extension was experimental, and thus not recommended, in the versions affected by this vulnerability. It has become enabled by default, and thus recommended, starting with XWiki 16.9.0. A user with only edit right can join a realtime editing session where others, that where already there or that may join later, have script or programming access rights. This user can then insert script rendering macros that are executed for those users in the realtime session that have script or programming rights. The inserted scripts can be used to gain more access rights. This vulnerability has been patched in XWiki 15.10.2, 16.4.1 and 16.6.0-rc-1. Users are advised to upgrade. Users unable to upgrade may either disable the realtime WYSIWYG editing by disabling the xwiki-realtime CKEditor plugin from the WYSIWYG editor administration section or uninstall the Realtime WYSIWYG Editorextension (org.xwiki.platform:xwiki-platform-realtime-wysiwyg-ui).

## Affected packages

- Maven `org.xwiki.platform:xwiki-platform-realtime-wysiwyg-ui` >= 13.9-rc-1, < 15.10.12 → fixed: 15.10.12
- Maven `org.xwiki.platform:xwiki-platform-realtime-wysiwyg-ui` >= 16.0.0-rc-1, < 16.4.1 → fixed: 16.4.1
- Maven `org.xwiki.platform:xwiki-platform-realtime-wysiwyg-ui` >= 16.5.0-rc-1, < 16.6.0-rc-1 → fixed: 16.6.0-rc-1

## Affected products (CVE record)

- xwiki xwiki-platform: >= 13.9-rc-1, < 15.10.12, >= 16.0.0, < 16.4.1, >= 16.5.0, < 16.6.0-rc-1

## Severity

- GitHub_M CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.0 `CVSS:3.1/AV:N/AC:L/PR:L/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 none , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.42% probability of exploitation activity in the next 30 days; percentile 35.
