Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), OffSeq Mirage (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 13 Nov 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade vite to 6.2.3.

AI-suggested

A patch is available for this vulnerability. Users should upgrade Vite to version 6.2.3 or later to remediate the issue. Until patched, avoid exposing the Vite dev server to the network (do not use --host or server.host to bind to external interfaces).

Description

A vulnerability in Vite allows bypassing the server.fs.deny restriction when using the ?raw?? or ?import&raw?? query parameters, enabling access to arbitrary file contents. This affects Vite dev servers explicitly exposed to the network via the --host option or server.host configuration. The issue arises because trailing separators in the query string are removed inconsistently, allowing unauthorized file reads outside the allowed serving paths. A proof of concept demonstrates reading sensitive files such as /tmp/secret.txt. The vulnerability affects Vite versions from 2.5.1 up to but not including 6.2.3. A patch is available to address this issue. The CVSS score is 5.3 (medium severity).

Impact

An attacker can read arbitrary files on the server running the Vite dev server if it is exposed to the network. This can lead to disclosure of sensitive information. The impact is limited to setups where the Vite dev server is explicitly exposed externally. There is no indication of remote code execution or integrity impact. The CVSS vector indicates network attack vector, high attack complexity, no privileges required, user interaction required, scope unchanged, and high confidentiality impact.

Summary

Vite's file serving mechanism includes a deny list (server.fs.deny) to restrict access to files outside allowed directories. However, when URLs include the query parameters ?raw?? or ?import&raw??, the trailing question marks are stripped inconsistently, bypassing the regex checks that enforce the deny list. This allows an attacker to retrieve arbitrary file contents from the server if the Vite dev server is exposed to the network (via --host or server.host config). The vulnerability affects versions >=2.5.1 and <6.2.3. A fix has been released to correct the query string handling and enforce proper access restrictions.
