Blinko through 1.8.8 Private Attachment Read via /api/file Route
Blinko through 1.8.8 contains a broken access control vulnerability in the /api/file route that allows authenticated users to read other users' private attachments due to a flawed owner check. Attackers can supply another user's stored filename, following a basename plus millisecond-timestamp pattern, to download private, non-shared attachments.
