    Summary: Padloc through 4.3.0 Missing SCIM Token Validation via SCIM GET Requests

    Details: Padloc through 4.3.0 contains a missing authentication vulnerability in ScimServer._handleScimGet() that allows unauthenticated attackers to read SCIM directories by sending any non-empty bearer token. Attackers who know an organization id can query the Users and Groups SCIM endpoints to retrieve provisioned usernames, emails, names, externalIds, and group memberships.
