EspoCRM: Access control bypass in Mass Update letting regular user with Mass Update permission read any attachment
Type: advisorySources: OSV
EspoCRM is an open source customer relationship management application. Prior to 10.0.2, an authenticated user with mass-update permission can supply a known attachment identifier to the mass-update functionality. The mass-update processor duplicates the attachment without checking whether the caller can read it, bypassing record-level and field-level restrictions and exposing the file contents through the copied attachment. Obtaining a valid attachment identifier may be difficult. This issue is fixed in version 10.0.2.
