What is CVE-2026-126935?

In versions of Zipline prior to 4.8.0, a race condition exists that allows remote attackers to bypass the maximum views limit set on files. This vulnerability occurs in the src/server/routes/raw/[id].ts file, enabling attackers to exploit non-atomic view counting mechanisms. By issuing simultaneous requests for the same file link, attackers can manipulate the view count, allowing them to access view-limited files or files that are set to be deleted after reaching the view limit.
