Technical details
A broken access control vulnerability in the vendor document endpoints validates only company_id scope rather than verifying vendor ownership of documents. Attackers with valid vendor-portal authentication can enumerate sequential Hashids (due to default empty HASH_SALT) and request GET /vendor/documents/{hashid}/download or POST /vendor/documents/download_multiple to read any document within the company, including invoices, contracts, and expense attachments.
