Technical details
This is an authorization bypass vulnerability in the contact management component caused by insufficient access control checks. The vulnerability exists in the ContactRepository::save() and ContactExportVCard::export() functions, which retrieve and modify contact records without filtering by the authenticated user's company_id. An authenticated user can craft requests with arbitrary contact numeric identifiers to overwrite contact data (name, phone, email, job title, notes) belonging to other companies, or export contacts as vCard files to exfiltrate personally identifiable information (PII). The vulnerability requires authentication but allows blind writes and information disclosure of other organizations' data. The fix filters queries by company_id to enforce proper tenant isolation; patches were released in version 5.4.8 and later.
