Attack profile from CVSS 3.1 · CNA. Fix status from CNA and Red Hat. Impact type from CWE-79.
Summary
A flaw was found in the Quay registry. While the image labels created through Quay undergo validation both in the UI and backend by applying a regex (validation.py), the same validation is not performed when the label comes from an image. This flaw allows an attacker to publish a malicious image to a public registry containing a script that can be executed via Cross-site scripting (XSS).
