CVE-2025-43736

A Denial Of Service via File Upload (DOS) vulnerability in Liferay Portal 7.4.3.0 through 7.4.3.132, Liferay DXP 2025.Q1.0 through 2025.Q1.8, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.0 through 2024.Q3.13, 2024.Q2.0 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.16 and 7.4 GA through update 92 allows a user to upload a profile picture of more than 300kb into a user profile. This size is more than the noted max 300kb size. This extra data can significantly slow down the Liferay service.

The application allocates resources such as memory, threads, or file descriptors based on untrusted input without enforcing a cap. Typical impact: resource exhaustion leading to denial of service.

4. Is CVE-2025-43736 exploitable, and should I be worried? Whether CVE-2025-43736 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.

5. What actually determines whether CVE-2025-43736 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.
