Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
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.
