Overview

go.pinniped.dev/internal/upstreamldap is an implements an abstraction of upstream LDAP IDP interactions.

Affected versions of this package are vulnerable to LDAP Injection in the Pinniped Supervisor with either LDAPIdentityProvider or ActiveDirectoryIdentityProvider resources. An attack would involve the malicious user changing the common name (CN) of their user entry on the LDAP or AD server to include special characters, which could be used to perform LDAP query injection on the Supervisor's LDAP query which determines their Kubernetes group membership.
