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: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to 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 2026-10-26.

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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC 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

The primary and most effective mitigation is to upgrade Mist Community Edition to version 4.7.2 or later, which contains the official patch addressing this XSS vulnerability. Organizations should verify their current version and plan an immediate upgrade. In addition, as an interim measure, administrators can implement web application firewalls (WAFs) with rules designed to detect and block malicious payloads targeting the 'tag' parameter in requests to the tag_resources function. Input validation and output encoding should be enforced on the server side to sanitize user-supplied data, although this requires code changes if upgrading is not immediately feasible. Network segmentation and restricting access to the Mist management interface to trusted IP ranges can reduce exposure. Educating users and administrators about the risks of clicking untrusted links and monitoring logs for suspicious activity related to the tag_resources endpoint can also help detect attempted exploitation. Finally, organizations should review their incident response plans to include scenarios involving XSS attacks on management interfaces.

Description

A vulnerability was found in Mist Community Edition up to 4.7.1. It has been rated as problematic. This issue affects the function tag_resources of the file src/mist/api/tag/views.py. The manipulation of the argument tag leads to cross site scripting. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. Upgrading to version 4.7.2 is able to address this issue. The patch is named db10ecb62ac832c1ed4924556d167efb9bc07fad. It is recommended to upgrade the affected component.

Impact

For European organizations using Mist Community Edition, this vulnerability poses a moderate risk. Since Mist Community Edition is a network management tool often used for wireless infrastructure management, exploitation could lead to unauthorized actions such as session hijacking, theft of sensitive information, or manipulation of network management interfaces. This could disrupt network administration workflows or lead to further compromise if attackers leverage the XSS to deploy more advanced attacks like phishing or malware delivery. The impact is particularly relevant for organizations with web-facing management consoles or those that allow remote access to the Mist interface. Confidentiality and integrity of administrative sessions and data could be compromised, potentially affecting compliance with European data protection regulations such as GDPR if personal or sensitive data is exposed. However, the lack of known active exploits and the medium severity rating suggest that while the threat is real, it is not currently critical. Organizations should prioritize patching to prevent potential exploitation, especially in sectors with high security requirements such as finance, healthcare, and critical infrastructure.

Summary

CVE-2025-5411 is a cross-site scripting (XSS) vulnerability identified in Mist Community Edition versions up to 4.7.1. The vulnerability resides in the function tag_resources within the source file src/mist/api/tag/views.py. Specifically, the issue arises from improper sanitization or validation of the 'tag' argument, which can be manipulated by an attacker to inject malicious scripts. This flaw allows an attacker to craft a specially crafted request that, when processed by the vulnerable function, results in the execution of arbitrary JavaScript code in the context of the victim's browser. The attack vector is remote and does not require authentication, but it does require user interaction (e.g., the victim must visit a maliciously crafted URL or interact with a compromised interface). The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits are currently reported in the wild. The vendor has addressed the issue in version 4.7.2 with a patch identified by commit db10ecb62ac832c1ed4924556d167efb9bc07fad. The CVSS v4.0 base score is 5.1, indicating a medium severity level. The vulnerability impacts confidentiality and integrity to a limited extent by enabling script execution that could lead to session hijacking, defacement, or redirection to malicious sites. Availability is not directly impacted. The vulnerability is exploitable without privileges but requires user interaction, which somewhat limits its impact scope.
