Zipline through 4.3.2 contains a path traversal vulnerability that allows authenticated uploaders to write files outside the upload directory by supplying traversal sequences in the x-zipline-filename header. Attackers using the local datasource can create or overwrite files writable by the Zipline process, corrupting application data or disrupting service.

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.

Zipline through 4.4.0 contains a path traversal vulnerability that allows authenticated users to read arbitrary server files by abusing a fallback treating the :id parameter as a datasource key. Attackers can send encoded traversal sequences in the :id of GET /api/user/files/:id/raw to escape the Local datasource uploads directory and read files like /etc/shadow.

Zipline before 4.6.4 contains an information disclosure vulnerability in GET /api/server/folder/:id that allows unauthenticated attackers to list files in non-public upload-only folders. Attackers who know the folder UUID can supply the page query parameter to bypass the metadata-only early return and enumerate file names, IDs, MIME types, sizes, and view counts.

Zipline before 4.8.0 contains a race condition vulnerability in src/server/routes/raw/[id].ts that allows remote attackers to bypass file maxViews limits through non-atomic view counting. Attackers holding a file link can send parallel requests that read the same pre-increment count, viewing view-limited or delete-on-max-views files beyond their limit.

Zipline 4.0.0 before 4.8.0 contains an upload filter bypass vulnerability that allows users with upload access to store blocked file types due to extension format mismatch. The upload and partial handlers compare dotted, case-sensitive extensions against undotted disabledExtensions entries, letting authenticated or permitted unauthenticated folder uploaders bypass administrator restrictions.
