CVE-2026-126932

5.3 MEDIUM Fix listed Code execution

What it is

Zipline 4.6.2 before 4.8.0 contains a policy bypass vulnerability that allows authenticated users to evade administrator-disabled MIME types by editing file metadata. Attackers can upload a permitted file, then set a disabled type such as text/html through PATCH /api/user/files/:id so /raw/:id serves that Content-Type.
