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.

Detectable: no evidence on record.

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 26 Oct 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.
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

To mitigate this vulnerability, European organizations should immediately upgrade Mist Community Edition to version 4.7.2 or later, where the issue has been patched. If upgrading is not immediately feasible, organizations should implement input validation and output encoding on the 'return_to' parameter to prevent script injection. Web application firewalls (WAFs) can be configured to detect and block suspicious payloads targeting this parameter. Additionally, organizations should educate users about the risks of clicking on untrusted links and monitor authentication logs for unusual activity that might indicate exploitation attempts. Regular security assessments and penetration testing focusing on authentication endpoints can help identify residual risks. Finally, organizations should ensure that their incident response plans include procedures for handling XSS incidents and potential session hijacking scenarios.

Description

A vulnerability classified as problematic has been found in Mist Community Edition up to 4.7.1. Affected is the function Login of the file src/mist/api/views.py of the component Authentication Endpoint. The manipulation of the argument return_to leads to cross site scripting. It is possible to launch the attack 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 name of the patch is db10ecb62ac832c1ed4924556d167efb9bc07fad. It is recommended to upgrade the affected component.

Impact

For European organizations using Mist Community Edition, this vulnerability poses a moderate risk. The primary impact is on the confidentiality and integrity of user sessions and data accessed through the affected authentication endpoint. Successful exploitation could allow attackers to hijack user sessions, redirect users to malicious sites, or perform actions on behalf of authenticated users, potentially leading to unauthorized access or data leakage. Organizations in sectors with sensitive data or regulatory requirements (such as finance, healthcare, or government) could face compliance issues if user data is compromised. Additionally, the remote exploitability without authentication increases the attack surface. However, the requirement for user interaction limits automated exploitation. The medium severity rating reflects these factors. Given the public disclosure of the exploit, European entities should prioritize remediation to prevent targeted attacks, especially in environments where Mist Community Edition is exposed to the internet or used by many users.
