# CVE-2024-26266: Liferay Portal and Liferay DXP vulnerable to stored Cross-site Scripting

**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 0.6% , percentile 46: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 46% 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 com.liferay.portal:release.portal.bom (Maven) <= 7.4.3.13, fixed in 7.4.3.14 ; com.liferay.portal:release.dxp.bom (Maven) >= 7.4.13.u1, < 7.4.13.u10, fixed in 7.4.13.u10 ; com.liferay.portal:release.dxp.bom (Maven) >= 7.3.10.ep3, < 7.3.10.u4, fixed in 7.3.10.u4 ; com.liferay.portal:release.dxp.bom (Maven) >= 7.2.0, < 7.2.10.fp17, fixed in 7.2.10.fp17 . Check your lockfile, including transitive dependencies.

## What it is

Multiple stored cross-site scripting (XSS) vulnerabilities in Liferay Portal 7.2.0 through 7.4.3.13, and older unsupported versions, and Liferay DXP 7.4 before update 10, 7.3 before update 4, 7.2 before fix pack 17, and older unsupported versions allow remote authenticated users to inject arbitrary web script or HTML via a crafted payload injected into the first/middle/last name text field of the user who creates an entry in the (1) Announcement widget, or (2) Alerts widget.

## Affected packages

- Maven `com.liferay.portal:release.portal.bom` <= 7.4.3.13 → fixed: 7.4.3.14
- Maven `com.liferay.portal:release.dxp.bom` >= 7.4.13.u1, < 7.4.13.u10 → fixed: 7.4.13.u10
- Maven `com.liferay.portal:release.dxp.bom` >= 7.3.10.ep3, < 7.3.10.u4 → fixed: 7.3.10.u4
- Maven `com.liferay.portal:release.dxp.bom` >= 7.2.0, < 7.2.10.fp17 → fixed: 7.2.10.fp17

## Affected products (CVE record)

- Liferay Portal: 7.2.0 <= 7.4.3.13
- Liferay DXP: 7.4.13 <= 7.4.13.u9, 7.3.10 <= 7.3.10-dxp-3, 7.2.10 <= 7.2.10-dxp-16

## Severity

- Liferay CVSS 3.1: 9 `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 partial .
- FIRST EPSS (model of 2026-10-21): 0.56% probability of exploitation activity in the next 30 days; percentile 46.
