Description
A flaw was found in Red Hat Quay's handling of resumable container image layer uploads. The upload process stores intermediate data in the database using a format that, if tampered with, could allow an attacker to execute arbitrary code on the Quay server.
Weaknesses (CWE)
- CWE-502 — Deserialization of Untrusted Data
