CVE-2026-111650 in ChronoFrame
Summary
by MITRE • 10/16/2026
ChronoFrame through 1.0.0 contains a missing authentication vulnerability in the server/api/wizard/ handlers that allows unauthenticated attackers to reconfigure already configured instances. Attackers can POST to /api/wizard/storage to activate an attacker-controlled S3 or OpenList provider, redirecting uploads and storage reads, and overwrite site and map settings.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The vulnerability identified in ChronoFrame versions up to 1.0.0 represents a critical failure in access control mechanisms within the application's server-side API logic. Specifically, the handlers located at /api/wizard/ fail to enforce authentication requirements for operations that modify system configuration and data storage settings. This missing authentication flaw allows any unauthenticated actor on the network or internet, depending on exposure, to interact with these endpoints directly without providing valid credentials. The core technical issue lies in the absence of middleware or route-level checks that verify user session validity or administrative privileges before processing state-changing requests. By exploiting this gap, an attacker can bypass intended security boundaries and execute privileged actions as if they were a legitimate administrator.
The operational impact of this vulnerability is severe due to the nature of the affected endpoints. The /api/wizard/storage endpoint allows for the reconfiguration of storage providers. An attacker can POST malicious configuration data to activate an S3 or OpenList provider controlled by them. This effectively redirects all subsequent uploads and read operations from the legitimate storage backend to a location under the attacker's control. Such redirection facilitates significant data exfiltration, as sensitive files uploaded through ChronoFrame are stored on compromised infrastructure rather than secure servers. Furthermore, the ability to overwrite site and map settings implies that an attacker can alter the fundamental behavior of the application interface, potentially leading to defacement, phishing page injection via manipulated maps or sites, or complete disruption of service availability by pointing configurations to non-existent or malicious endpoints.
From a classification perspective, this vulnerability aligns with CWE-287, which denotes Improper Authentication, as the system fails to correctly verify identity before granting access to sensitive functions. It also relates closely to CWE-601, URL Redirection to Untrusted Site, given the capability to redirect storage operations to attacker-controlled domains via S3 or OpenList configurations. In terms of attack vectors and tactics, this exploitation maps directly to MITRE ATT&CK technique T1528, Steal Application Access Token, although in this specific case, no token is stolen because none are required due to the authentication bypass. More accurately, it fits within T1078, Valid Accounts, if we consider that the attacker gains administrative capabilities without valid credentials, and potentially T1496, Resource Hijacking or Data Exfiltration over C2 channels if the redirected storage is used for command and control infrastructure setup. The lack of input validation on these endpoints may also introduce secondary risks such as CWE-73, External Control of File Name or Path, depending on how the provider configurations are parsed internally.
To mitigate this vulnerability, immediate remediation should focus on enforcing strict authentication checks on all API endpoints that modify system configuration or handle sensitive data operations. Developers must implement middleware in the server/api/wizard/ handlers to verify valid user sessions and ensure that only users with explicit administrative roles can access these routes. Additionally, implementing role-based access control (RBAC) ensures that even if an attacker bypasses basic authentication, they cannot perform actions outside their assigned permissions. Input validation should be strengthened to sanitize configuration data passed via POST requests, preventing the injection of malicious provider URLs or settings. Regular security audits and penetration testing focusing on API endpoints are recommended to identify similar gaps in access control logic across other parts of the application infrastructure.
