Summary
Liferay Portal Vulnerable to Cross-Site Scripting
A reflected cross-site scripting (XSS) vulnerability in the Liferay Portal 7.4.3.132, and Liferay DXP 2025.Q1.0 through 2025.Q1.7 allows a remote authenticated attacker to inject JavaScript code via the content page's name field. This malicious payload is then reflected and executed within the user's browser when viewing the "document View Usages" page.
Liferay Portal is fixed on the master branch from commit 2135a88.
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-2025-43733? CVE-2025-43733 is a low-severity cross-site scripting (XSS) vulnerability in com.liferay:com.liferay.layout.taglib (maven), affecting versions < 17.0.0. It is fixed in 17.0.0. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
- Which versions of com.liferay:com.liferay.layout.taglib are affected by CVE-2025-43733? com.liferay:com.liferay.layout.taglib (maven) versions < 17.0.0 is affected.
- Is there a fix for CVE-2025-43733? Yes. CVE-2025-43733 is fixed in 17.0.0. Upgrade to this version or later.
- Is CVE-2025-43733 exploitable, and should I be worried? Whether CVE-2025-43733 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-2025-43733 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.
- How do I fix CVE-2025-43733? Upgrade
com.liferay:com.liferay.layout.taglibto 17.0.0 or later.
