# CVE-2023-44311: Liferay Portal and Liferay DXP Vulnerable to XSS via the OAuth2ProviderApplicationRedirect Class

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (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 a user to click or open something. Phishing makes that realistic, but it is not wormable.
- Only applies if your dependency tree includes com.liferay:com.liferay.oauth2.provider.rest (Maven) < 4.0.51, fixed in 4.0.51 ; com.liferay.portal:release.dxp.bom (Maven) >= 7.4.13.u41, < 7.4.13.u90, fixed in 7.4.13.u90 . Check your lockfile, including transitive dependencies.

## What it is

Multiple reflected cross-site scripting (XSS) vulnerabilities in the Plugin for OAuth 2.0 module's OAuth2ProviderApplicationRedirect class in Liferay Portal 7.4.3.41 through 7.4.3.89, and Liferay DXP 7.4 update 41 through update 89 allow remote attackers to inject arbitrary web script or HTML via the (1) code, or (2) error parameter. This issue is caused by an incomplete fix in CVE-2023-33941.

## Affected packages

- Maven `com.liferay:com.liferay.oauth2.provider.rest` < 4.0.51 → fixed: 4.0.51
- Maven `com.liferay.portal:release.dxp.bom` >= 7.4.13.u41, < 7.4.13.u90 → fixed: 7.4.13.u90

## Affected products (CVE record)

- Liferay DXP: 7.4.13.u41 <= 7.4.13.u89
- Liferay Portal: 7.4.3.41 <= 7.4.3.89

## Severity

- Liferay CVSS 3.1: 9.6 `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.6 `CVSS:3.1/AV:N/AC:L/PR:N/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): 0.57% probability of exploitation activity in the next 30 days; percentile 46.
