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: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
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: None: The vulnerable system can be exploited without any interaction from any user.
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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 13 Aug 2026
Detectable: no evidence on record.
No public nuclei template indexed

A missing step is not evidence of safety. Sources: cve.org (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 5.4.6.

AI-suggested

A patch is available for this vulnerability. Users should upgrade Vite to version 5.4.6 or later to remediate this issue. Until patched, avoid exposing Vite development servers to untrusted networks.

Description

Vite versions from 2.5.1 up to but not including 5.4.6 contain a vulnerability where the server's file system access restrictions can be bypassed using the '?import&raw' query parameters. This allows an attacker to retrieve the contents of arbitrary files outside the intended serving allow list. The vulnerability has a medium severity with a CVSS score of 5.3.

Impact

An attacker can read arbitrary files on the server that are outside the intended allowed directories, potentially exposing sensitive information. The vulnerability does not allow modification or denial of service but compromises confidentiality.

Summary

The vulnerability in Vite arises because the '@fs' file system access control, which denies access to files outside the configured allow list, can be bypassed by appending '?import&raw' to the URL. This bypass causes the server to return the raw content of arbitrary files if they exist, exposing potentially sensitive data. A proof of concept demonstrates that while direct access to a file outside the allow list results in a 403 error, adding '?import&raw' returns the file content as a JavaScript export.
