Upgrade node to version 26.12.1 or higher.
Overview
node is a JavaScript runtime built on Chrome's V8 JavaScript engine.
Affected versions of this package are vulnerable to Improper Cleanup on Thrown Exception via the lazy local-header resolver in ZipEntry in lib/internal/zip/entry.js. An attacker can make an application return attacker-controlled prefix bytes as a file-backed ZIP entry’s content by supplying an archive with a local header that fails validation against the central directory; after the initial read fails, a later read uses the file descriptor’s current position because the entry retains a cached header but an unresolved content offset. This affects Node.js 26.x; version 26.12.1 is patched.
