## What is CVE-2025-32959?

CVE-2025-32959 is a medium-severity denial of service vulnerability in cuba-platform cuba, published on 22 Apr 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

CUBA Platform is a high level framework for enterprise applications development. Prior to version 7.2.23, 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. This issue has been patched in version 7.2.23. A workaround is provided on the Jmix documentation website.

Weakness: CWE-770 (Allocation of Resources Without Limits or Throttling)
