Summary
Liferay Portal's Unlimited File Upload Could Result in DoS
Liferay Portal 7.4.0 through 7.4.3.132, and Liferay DXP 2025.Q1.0 through 2025.Q1.4, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.0 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.15 and 7.4 GA through update 92 allow users to upload an unlimited amount of files through the object entries attachment fields, the files are stored in the document_library allowing an attacker to cause a potential DDoS.
Impact
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.

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.

In the interim: Apply per-request resource limits and enforce them before allocation. Rate-limit callers at the network or application layer.

Frequently Asked Questions
- What is CVE-2025-43752? CVE-2025-43752 is a medium-severity allocation of resources without limits or throttling vulnerability in com.liferay.portal:release.portal.bom (maven), affecting versions >= 7.4.0-ga1, <= 7.4.3.132-ga132. No fixed version is listed yet. The application allocates resources such as memory, threads, or file descriptors based on untrusted input without enforcing a cap.
- Which versions of com.liferay.portal:release.portal.bom are affected by CVE-2025-43752? com.liferay.portal:release.portal.bom (maven) versions >= 7.4.0-ga1, <= 7.4.3.132-ga132 is affected.
- Is there a fix for CVE-2025-43752? No fixed version is listed for CVE-2025-43752 yet. Monitor the advisory for updates and apply mitigations in the interim.
- Is CVE-2025-43752 exploitable, and should I be worried? Whether CVE-2025-43752 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-2025-43752 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-2025-43752? No fixed version is listed yet. In the interim: Apply per-request resource limits and enforce them before allocation. Rate-limit callers at the network or application layer.
