Official description

Dolibarr before 24.0.0 contains a broken object-level authorization vulnerability in the REST API company bank account write routes that allows authenticated attackers with third-party creation rights to create, replace, or delete bank account details of any company without requiring read access to that company. Attackers can inject attacker-controlled IBANs as creditor accounts, which are then written into regenerated SEPA credit-transfer files, redirecting outgoing payments to attacker-controlled accounts.
