Harbor fails to validate user permissions when reading and updating job execution logs through the P2P preheat execution logs. By sending a request that attempts to read/update P2P preheat execution logs and specifying different job IDs, malicious authenticated users could read all the job logs stored in the Harbor database.

Harbor fails to validate the user permissions when updating tag retention policies.  By sending a request to update a tag retention policy with an id that belongs to a project that the currently authenticated user doesn’t have access to, the attacker could modify tag retention policies configured in other projects.

Harbor fails to validate the user permissions when updating tag immutability policies.  By sending a request to update a tag immutability policy with an id that belongs to a project that the currently authenticated user doesn’t have access to, the attacker could modify tag immutability policies configured in other projects.

Harbor fails to validate the user permissions when updating p2p preheat policies. By sending a request to update a p2p preheat policy with an id that belongs to a project that the currently authenticated user doesn't have access to, the attacker could modify p2p preheat policies configured in other projects.

Harbor fails to validate the user permissions when updating a robot account that belongs to a project that the authenticated user doesn’t have access to.  By sending a request that attempts to update a robot account, and specifying a robot account id and robot account name that belongs to a different project that the user doesn’t have access to, it was possible to revoke the robot account permissions.

Harbor fails to validate user permissions while deleting Webhook policies, allowing malicious users to view, update and delete Webhook policies of other users.  The attacker could modify Webhook policies configured in other projects.

Incorrect user permission validation in Harbor <v2.9.5 and Harbor <v2.10.3 allows authenticated users to modify configurations.

An access control issue in Harbor v1.X.X to v2.5.3 allows attackers to access public and private image repositories without authentication. NOTE: the vendor's position is that this "is clearly described in the documentation as a feature."

Cloud Native Computing Foundation Harbor before 1.10.3 and 2.x before 2.0.1 allows resource enumeration because unauthenticated API calls reveal (via the HTTP status code) whether a resource exists.

In Harbor 2.0 before 2.0.5 and 2.1.x before 2.1.2 the catalog’s registry API is exposed on an unauthenticated path.

Harbor 1.9.* 1.10.* and 2.0.* allows Exposure of Sensitive Information to an Unauthorized Actor.

Harbor prior to 2.0.1 allows SSRF with this limitation: an attacker with the ability to edit projects can scan ports of hosts accessible on the Harbor server's intranet.
