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.

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

Upgrade Vite to version 7.1.5 or later where this vulnerability is fixed. Until then, avoid exposing the Vite development or preview server to untrusted networks. No other mitigations are indicated by the vendor advisory.

Description

Vite versions from 2.5.1 up to but not including 7.1.5 have a vulnerability where the server.fs configuration settings are not applied to HTML files. This allows HTML files outside the allowed directories to be served by the development and preview servers if the server is exposed to the network. The issue arises because certain middleware serving HTML files bypass the file system access restrictions. This can lead to unauthorized disclosure of HTML files on the host machine.

Impact

An attacker able to access the Vite development or preview server over the network can retrieve arbitrary HTML files from the host filesystem, bypassing configured file system access restrictions. This may lead to unauthorized disclosure of sensitive HTML content. The impact is limited to setups explicitly exposing the Vite server to the network and using default or specified app types. The CVSS score is low (2.3), reflecting limited impact and attack complexity.

Summary

CVE-2025-58752 affects Vite development and preview servers by failing to enforce the server.fs allow/deny rules on HTML files. The static file serving middleware excludes HTML files from its access checks, passing requests to other middleware that serve HTML content without verifying if the file is within allowed directories. This flaw allows an attacker to retrieve arbitrary HTML files from the host filesystem if the Vite server is exposed to the network (e.g., via --host or server.host configuration). The vulnerability affects apps using appType 'spa' or 'mpa'. A proof of concept demonstrates reading arbitrary HTML files such as /tmp/secret.html. The issue is fixed in Vite version 7.1.5.
