CVE-2026-126935

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.
