In affected versions of Octopus Server, incorrect validation of the external identity linked to a newly registered user could result in that user receiving the LDAP-mapped team memberships and associated permissions of another user. This issue only affects instances with LDAP authentication enabled and LDAP groups mapped to Octopus teams.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
