Technical details
The vulnerability is a broken object-level authorization (BOLA) flaw in the REST API routes that handle company bank account write operations. Authenticated attackers with third-party creation rights can bypass authorization checks to create, replace, or delete bank account records for any company in the system without requiring read access to that company. The exploit involves injecting attacker-controlled IBAN numbers into company records, which are then embedded in regenerated SEPA credit-transfer files used for automated payment processing. The vulnerability was fixed in version 24.0.0 as documented in GitHub commit c100564.
