Overview
Recently, NSFOCUS CERT detected that Vite issued a security announcement and fixed the arbitrary file reading vulnerability of Vite (CVE-2025-30208). Since the Vite development server does not strictly verify the path when processing URL requests, unauthenticated attackers can bypass path access restrictions by constructing special URLs to obtain sensitive files outside the project root directory. At present, the vulnerability details and PoC have been made public. Relevant users are requested to take measures for protection as soon as possible.
NSFOCUS has successfully replicated this vulnerability:
