Docker has disclosed a critical vulnerability (CVE-2026-105445) in Docker Hub that let attackers access another user’s container repositories using a personal access token (PAT).
Docker Hub is an online registry for storing, sharing, and downloading container images - templates that package everything needed for an application to run in an isolated environment.
In Docker Hub, a PAT serves as a secret used to authenticate tools and workflows. It allows you to pull, push, or delete container images.
