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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: Present: The successful attack depends on the presence of specific deployment and execution conditions of the vulnerable system that enable the attack. These include: a race condition must be won to successfully exploit the vulnerability (the successfulness of the attack is conditioned on execution conditions that are not under full control of the attacker, or the attack may need to be launched multiple times against a single target before being successful); the attacker must inject themselves into the logical network path between the target and the resource requested by the victim (e.g. vulnerabilities requiring an on-path attacker).
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system 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 Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

Exploitation evidence

Disclosed: evidence found.
CVE published 8 Sep 2025
Detectable: evidence found.
nuclei template: Vite Dev Server - Path Traversal
Weaponized: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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.

AI-suggested

A patch is available in Vite version 7.1.5 that fixes this vulnerability. Users should upgrade affected Vite versions (>=2.5.1 <7.1.5) to 7.1.5 or later. Until patched, avoid exposing the Vite dev server to the network or avoid using symbolic links in the public directory to mitigate the risk.

Description

Vite middleware serving files from the public directory may incorrectly serve files outside the intended directory when symbolic links exist in the public directory and the server is exposed to the network. This occurs due to a path normalization and prefix check flaw in the middleware, allowing path traversal to access files outside the public directory despite deny rules. The issue affects Vite versions from 2.5.1 up to but not including 7.1.5 and has a low severity rating.

Impact

An attacker can bypass file system access restrictions configured in Vite's server.fs deny list and retrieve arbitrary files outside the public directory when the Vite dev server is exposed to the network and symbolic links exist in the public directory. This could lead to unauthorized disclosure of sensitive files on the server hosting the Vite dev environment. The impact is limited to development environments explicitly exposed to the network and using the public directory with symlinks.

Summary

The vulnerability in Vite's servePublicMiddleware arises because when symbolic links exist in the public directory, the publicFiles variable becomes undefined, causing all requests to be treated as public and bypassing the server.fs deny list. The middleware uses the sirv library to serve files, which checks if the requested file path starts with the public directory path. However, sirv trims trailing slashes, and the startsWith check can be bypassed using path traversal sequences (e.g., '../') that normalize outside the public directory but still pass the startsWith check. This allows an attacker to request files outside the public directory, such as private files, if the Vite dev server is exposed to the network and uses the public directory feature with symbolic links present.
