# CVE-2023-42628: Liferay Portal and Liferay DXP Vulnerable to XSS in the Wiki Widget

**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. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 2.8% , percentile 86: FIRST’s model estimates a 2.8% chance of exploitation activity in the next 30 days, higher than 86% of all scored CVEs (elevated). 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 com.liferay:com.liferay.wiki.web (Maven) < 7.0.95, fixed in 7.0.95 ; com.liferay.portal:release.dxp.bom (Maven) >= 7.0.10.fp83, <= 7.0.10.fp102, no fixed version listed ; com.liferay.portal:release.dxp.bom (Maven) >= 7.1.0, <= 7.1.10.fp28, no fixed version listed ; com.liferay.portal:release.dxp.bom (Maven) >= 7.2.0, <= 7.2.10.fp20, no fixed version listed . Check your lockfile, including transitive dependencies.

## What it is

Stored cross-site scripting (XSS) vulnerability in the Wiki widget in Liferay Portal 7.1.0 through 7.4.3.87, and Liferay DXP 7.0 fix pack 83 through 102, 7.1 fix pack 28 and earlier, 7.2 fix pack 20 and earlier, 7.3 update 33 and earlier, and 7.4 before update 88 allows remote attackers to inject arbitrary web script or HTML into a parent wiki page via a crafted payload injected into a wiki page's ‘Content’ text field.

- 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).
- FIRST EPSS (model of 2026-10-21): 2.78% probability of exploitation activity in the next 30 days; percentile 86.
