Summary
Liferay Portal 7.4.0 and Liferay DXP have a reflected cross-site scripting (XSS) vulnerability
A reflected cross-site scripting (XSS) vulnerability in the Liferay Portal 7.4.0 through 7.4.3.132, and Liferay DXP 2025.Q1.0 through 2025.Q1.10, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.1 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.16 and 7.4 GA through update 92 allows a remote authenticated attacker to inject JavaScript code in the “first display label” field in the configuration of a custom sort widget. This malicious payload is then reflected and executed by clay button taglib when refreshing the page.
Impact
Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2025-43734? CVE-2025-43734 is a medium-severity cross-site scripting (XSS) vulnerability in com.liferay.portal:release.portal.bom (maven), affecting versions >= 7.4.0, <= 7.4.3.132. It is fixed in 2024.q1.17, 2025.q1.11, 15.2.2. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
- Which packages are affected by CVE-2025-43734?
com.liferay.portal:release.portal.bom(maven) (versions >= 7.4.0, <= 7.4.3.132)com.liferay.portal:release.dxp.bom(maven) (versions >= 2024.q4.0, <= 2024.q4.7)com.liferay:com.liferay.frontend.taglib.clay(maven) (versions < 15.2.2)
- Is there a fix for CVE-2025-43734? Yes. CVE-2025-43734 is fixed in 2024.q1.17, 2025.q1.11, 15.2.2. Upgrade to this version or later.
- Is CVE-2025-43734 exploitable, and should I be worried? Whether CVE-2025-43734 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2025-43734 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
