Description

EdgeChat before 2.20.3 contains a missing authentication vulnerability in the GET /files/:key route that allows unauthenticated or banned users to download decrypted public-channel attachments because canAccessFile() accepts a null user id. Attackers holding an attachment object key can omit or supply an invalid token to retrieve plaintext attachments without a session or channel membership.
