CVE-2020-10952Network attack vector

Container image read and write via blocked-state bypass

Published Mar 27, 2020 · Updated Aug 4, 2024

Incorrect authorization in GitLab EE/CE 8.11 through 12.9.1 allows blocked remote authenticated users to pull or push container images. The container registry authorization flow grants pull and push access without enforcing the account's blocked state. A blocked account with valid registry credentials can therefore read existing images or write replacement images in previously accessible repositories.
