Pinniped Supervisor 0.11-0.46 Elevates Cluster Privileges via AD DN Edit
CVE-2026-59269 Published on July 9, 2026
Privilege Escalation via Active Directory LDAP injection in Pinniped Supervisor can be executed by an attacker who can edit LDAP Group DN entries
A user authenticating to Kubernetes clusters via the Pinniped Supervisor could potentially gain elevated permissions in the clusters, only if all the following conditions were true: the Pinniped Supervisor server is running with an ActiveDirectoryIdentityProvider resource configured; the ActiveDirectoryIdentityProvider.spec.groupSearch.attributes.groupName is empty; the attacker gains the ability to edit some part of the distinguished name (DN) of group entries in the Active Directory (AD) server's database for groups to which they belong; the configured group search parameters cause the edited group to be included in the group search results for the user; and the attacker knows the password for an AD user who belongs to the edited AD group.
Affected versions: Pinniped (go.pinniped.dev) v0.11.0 through v0.46.0 inclusive; fixed in v0.47.0.
