CVE-2023-44309: Liferay Portal and Liferay DXP Vulnerable to XSS in the Fragment Components

Should you act?

Critical, preconditions apply

Severe if exploited, but exploitation needs conditions that may not apply to you. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• 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 47: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 47% 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:com.liferay.fragment.entry.processor.impl (Maven) < 3.0.25, fixed in 3.0.25; com.liferay.portal:release.dxp.bom (Maven) >= 7.4.0, < 7.4.13.u54, fixed in 7.4.13.u54. Check your lockfile, including transitive dependencies.

What it is

Multiple stored cross-site scripting (XSS) vulnerabilities in the fragment components in Liferay Portal 7.4.2 through 7.4.3.53, and Liferay DXP 7.4 before update 54 allow remote attackers to inject arbitrary web script or HTML via a crafted payload injected into any non-HTML field of a linked source asset.

From the GitHub advisory

Multiple stored cross-site scripting (XSS) vulnerabilities in the fragment components before 3.0.25 from Liferay Portal (7.4.2 through 7.4.3.53), and Liferay DXP 7.4 before update 54 allow remote attackers to inject arbitrary web script or HTML via a crafted payload injected into any non-HTML field of a linked source asset.

Weakness type: CWE-79.

Product: com.liferay:com.liferay.fragment.entry.processor.impl (Maven) · Assigned by: Liferay · Published: 2023-10-17

Affected and fixed versions

Severity scores

• Attack vector: network (remotely reachable)
• Attack complexity: low
• Privileges required: low (any account)
• User interaction: required (a user must click/open something)
• Scope: changed (can affect other components)

CVSS measures how bad a flaw is if exploited, not how likely exploitation is. Read it next to the exploitation data below.

Exploitation and urgency

• 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 47.
