What is MAL-2026-17418?

Official description
On October 10, 2026 (local time), boom() calls localStorage.setItem('key', i) 100,000,000 times in a synchronous loop, potentially freezing a browser page. In version 0.0.2, the exported getCommonDateInRanges() calls boom() before input validation; the bundled source map confirms this path. Version 0.0.3 retains boom() as a separate export but no longer calls it from getCommonDateInRanges(), so an explicit call is required. Version 0.0.1 does not contain this routine. This is a static finding; actual victim impact was not observed.
What should I do about MAL-2026-17418?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
