CVE-2026-105445— Docker Hub account conversion could reassign an active personal access token to another user

Quick assessment

Affected
Docker Docker Hub
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Docker Hub 的“个人账户转换为组织账户”功能中存在一处权限分配错误漏洞，该漏洞允许经过身份验证的攻击者将其控制的个人访问令牌（PAT）重新分配给另一个 Docker Hub 用户，而无需轮换或撤销该令牌的密钥。未被更改的 PAT 随后可以以接收者的身份向容器镜像注册服务进行身份验证，并在该用户可访问的仓库（包括组织仓库）中，在令牌所授权的作用域范围内执行拉取、推送或删除镜像等操作。

Vulnerability Title
Docker Hub account conversion could reassign an active personal access token to another user
Source: CVE Program / CVE List V5
Vulnerability Description
An Incorrect Privilege Assignment vulnerability in Docker Hub's account-to-organization conversion feature allowed an authenticated attacker to reassign a personal access token (PAT) they controlled to another Docker Hub user without rotating or revoking the token secret. The unchanged PAT then authenticated to the registry as the recipient and could pull, push, or delete images, within its scopes, in repositories accessible to that user, including organization repositories.
