CVE-2026-126950
Zipline through 4.4.0 Path Traversal Arbitrary File Delete via x-zipline-file-extension
Description

Zipline through 4.4.0 contains a path traversal vulnerability that allows authenticated attackers to delete arbitrary server files by injecting traversal sequences via the x-zipline-file-extension header. Attackers can upload a file with a poisoned stored name and short expiry so LocalDatasource deletion removes chosen files, causing denial of service or data loss.
