# CVE-2026-110311

> 4.3 MEDIUM · 🧪 PoC

## Beschreibung

Creating a draft release through the API returned an `assets` list that was built from a release without an ID, which matched every attachment that was not linked to a release. A user who could create a draft release in a repository therefore received the metadata (file name, UUID, upload time, size and download count) of issue and comment attachments of repositories they could not read, and of abandoned uploads.
