CVE-2025-30208 Overview
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.
Critical Impact
This vulnerability allows unauthorized access to sensitive files, potentially leading to information disclosure.

Technical Details for CVE-2025-30208
Vulnerability Analysis
The vulnerability stems from the ability to bypass @fs path restrictions by appending query separators such as ?raw??, allowing unauthorized retrieval of file contents from outside the allowed paths. This can lead to the unintended exposure of sensitive data if the Vite dev server is exposed to the network.
Root Cause
Trailing separators like ? are not properly accounted for in regular expressions that validate URLs, leading to bypasses of path restrictions.
Attack Vector
Network-based attackers can exploit this vulnerability by sending crafted URLs with specific query parameters to dev servers exposed with --host or server.host.
// Example exploitation code (sanitized)
fetch('http://vulnerable-site.local/@fs/sensitive-file.txt?raw??')
.then(response => response.text())
.then(data => console.log(data));
Detection Methods for CVE-2025-30208
Indicators of Compromise
- Unusual access logs with ?raw?? or ?import&raw??
- Unexplained file access patterns
- Unexpected sensitive data exposure
Detection Strategies
Monitoring server logs for suspicious URL patterns and conducting regular checks for unauthorized access attempts can help in early detection of exploitation attempts.
Monitoring Recommendations
Implement network-based intrusion detection systems (NIDS) to watch for crafted URLs containing query bypass patterns. Use SentinelOne’s endpoint protection platform to monitor and block unauthorized network connections.
How to Mitigate CVE-2025-30208
Immediate Actions Required
- Update Vite to versions 6.2.3, 6.1.2, 6.0.12, 5.4.15, or 4.5.10
- Restrict network exposure of the Vite dev server
- Monitor and review access logs for suspicious activity

Workarounds
Configure your server to restrict network exposure of the Vite dev server using firewall rules.
# Configuration example
iptables -A INPUT -p tcp --dport 3000 -s 192.168.1.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 3000 -j DROP
