How to Fix CVE-2025-32952

To remediate this vulnerability, upgrade all affected Jmix localfs dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

io.jmix.localfs:jmix-localfs fixed: 1.6.2 
<dependency>
    <groupId>io.jmix.localfs</groupId>
    <artifactId>jmix-localfs</artifactId>
    <version>1.6.2</version>
</dependency>
io.jmix.localfs:jmix-localfs fixed: 2.4.0 
<dependency>
    <groupId>io.jmix.localfs</groupId>
    <artifactId>jmix-localfs</artifactId>
    <version>2.4.0</version>
</dependency>
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=io.jmix.localfs

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2025-32952, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=io.jmix.localfs

Analyze the terminal output to locate any version of Jmix localfs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.6.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=io.jmix.localfs command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-770: Allocation of Resources Without Limits or Throttling, where the product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated. In Jmix localfs, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact The local file storage implementation does not restrict the size of uploaded files. An attacker could exploit this by uploading excessively large files, potentially causing the server to run out of space and return HTTP 500 error, resulting in a denial of service. The severity of the vulnerability is mitigated by the fact that the application UI and the generic REST API are typically accessible only to authenticated users. Additionally, the /files endpoint in Jmix requires specific permissions and is disabled by default. ### Patches The problem has been fixed in Jmix 1.6.2+ and 2.4.0+. ### Workarounds A workaround for those who are unable to upgrade: [Disable Files Endpoint in Jmix Application](https://docs.jmix.io/jmix/files-vulnerabilities.html#disable-files-endpoint-in-jmix-application).
