Link for people: https://infrastack.ai/live/CVE-2026-126948 (this .md is for agents)

## From the sources

Zipline before 4.5.0 contains an insecure direct object reference vulnerability caused by missing ownership verification in the PATCH and DELETE handlers for /api/user/folders/:id. Authenticated attackers can supply another user's folder ID to rename it, make it public, enable uploads, or delete it.
