# Dinky: catalogue upload path traversal lets remote users write files

Link for people: https://infrastack.ai/live/CVE-2026-124572 (this .md is for agents)

Dinky, a Java data platform, has a path traversal flaw in its catalogue upload API (CatalogueController.upload) in versions up to 1.2.5. A remote attacker can use crafted file paths to write files outside the intended directory.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed Dinky version in the deployment or build files; versions up to `1.2.5` are reported as affected.
- Confirm whether the Dinky admin service is reachable from the network, since the sources say the attack can be carried out remotely.
