CVE-2026-59269 Details
Description
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.
A privilege escalation vulnerability has been identified in Pinniped Supervisor versions 0.11.0 through 0.46.0, inclusive. This issue arises when the Pinniped Supervisor is configured with an Active Directory Identity Provider and the group name attribute is left empty. Under these conditions, an attacker with knowledge of an Active Directory user's password and the ability to edit group distinguished names could manipulate group entries to gain elevated permissions in Kubernetes clusters.
Users should upgrade to Pinniped Supervisor version 0.47.0 or later. For those using an Active Directory Identity Provider, it is also recommended to configure the group name attribute to a non-empty value. Additionally, preventing users from editing Active Directory LDAP group entries can mitigate this vulnerability.
