Real-World Exposure
io.jmix.localfs:jmix-localfs☕io.jmix.localfs:jmix-localfsReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
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.

Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for io.jmix.localfs:jmix-localfs, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update io.jmix.localfs:jmix-localfs to 1.6.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-32952 is resolved across your whole dependency graph.
Workarounds
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
