Description
Description
In affected versions of Octopus Server, incorrect validation of changes a user made to their own LDAP identity allowed them to edit that identity even when an Administrator had disabled self-service identity editing. This could result in the user gaining membership of teams mapped to external LDAP groups they do not belong to, and potentially escalating to full administrative privileges if any of those teams are privileged.
