CVE-2026-126938
Zipline before 4.6.4 Upload Quota Bypass via Forged Content-Range Headers
Description
Zipline before 4.6.4 contains a resource allocation vulnerability that allows authenticated users to bypass chunked-upload size and quota checks by forging Content-Range offsets and totals. Attackers can send tiny chunks to the partial upload endpoint with large declared offsets, causing the server to create oversized files and exhaust disk space.
