Denied-file disclosure via query-bearing module IDs
Published Apr 7, 2026 · Updated Apr 7, 2026
Information disclosure in VoidZero Vite+ before 0.1.16 allows remote attackers to read denied files through an exposed dev server. The transform middleware checks server.fs.deny against module IDs that still include query strings, so raw and import queries evade deny-pattern matching. Exploitation requires network exposure, a sensitive file inside server.fs.allow, and a matching server.fs.deny rule; successful requests disclose file contents without changing them.
