Description
CloudBeaver through 25.3.5 contains a missing authorization vulnerability in the initConnection GraphQL mutation that lets view-only shared-project members persist credentials without datasource-edit permission. Attackers can set saveCredentials and sharedCredentials flags with chosen authProperties so other users connect to the shared connection under the attacker's database identity.
