CVE-2025-30208
Published: April 11, 2026
Official Description
Vite, a provider of frontend development tooling, has a vulnerability in versions prior to 6.2.3, 6.1.2, 6.0.12, 5.4.15, and 4.5.10. `@fs` denies access to files outside of Vite serving allow list. Adding `?raw??` or `?import&raw??` to the URL bypasses this limitation and returns the file content if it exists. This bypass exists because trailing separators such as `?` are removed in several places, but are not accounted for in query string regexes. The contents of arbitrary files can be returned to the browser. Only apps explicitly exposing the Vite dev server to the network (using `--host` or `server.host` config option) are affected. Versions 6.2.3, 6.1.2, 6.0.12, 5.4.15, and 4.5.10 fix the issue.
Technical Analysis
CVE-2025-30208 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2025-30208 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
