- CVE-2026-80191High
GROWI applies its page-viewer permission check to attachment requests only when the request carries an authenticated user. retrieveAttachmentFromIdParam skips the check when the user is null, so a request without a session skips the check and returns the file. An unauthenticated attacker with an attachment identifier can download the file even if the page is private. Version 8.0.2 checks both authenticated and unauthenticated requests.
