Description
EspoCRM before 10.0.7 contains an insecure direct object reference vulnerability that allows authenticated users with Import scope access to read other users' attachments by supplying a foreign attachmentId to the Import endpoint. Attackers can create an Import record referencing a known attachment ID, then call the error export endpoint to copy source rows into a downloadable CSV they own.
