CVE-2026-102150 in Secure Data Forms
Summary
by MITRE • 10/01/2026
A function in the Kiteworks Advanced Forms component was reachable without authentication. An unauthenticated attacker could potentially use it to carry out a limited set of internal service operations on the Kiteworks platform; it did not permit access to user accounts, stored files, or form submissions.

The vulnerability identified in the Kiteworks Advanced Forms component represents a critical failure in authentication enforcement for specific application functions. This flaw allows unauthenticated actors to interact with internal service operations that are intended to be restricted to authorized users only. The core technical issue lies in the misconfiguration or omission of access control checks on certain endpoints within the advanced forms module, effectively exposing backend logic to public internet traffic without requiring valid credentials or session tokens.
From a technical perspective, this constitutes an insecure direct object reference combined with broken access control mechanisms. While the attacker cannot directly view sensitive data such as user accounts, stored files, or form submissions due to additional layered security controls within those specific data retrieval paths, they can still trigger internal processes. These processes may include state changes, resource allocation requests, or configuration updates that are not protected by standard authentication protocols. The lack of immediate access to high-value assets does not mitigate the severity of the flaw, as it provides a foothold for further exploitation attempts and disrupts the principle of least privilege.
The operational impact of this vulnerability is significant despite its limited scope regarding data exfiltration. An unauthenticated attacker can potentially cause denial-of-service conditions by flooding these internal endpoints with requests, leading to resource exhaustion on the server side. Furthermore, if any of the exposed operations involve modifying system configurations or triggering automated workflows, it could lead to integrity violations where unauthorized changes are made to the platform's behavior. This undermines the reliability and trustworthiness of the Kiteworks environment for legitimate users who depend on consistent service availability and correct operational states.
This vulnerability aligns with CWE-287 Improper Authentication and CWE-862 Missing Authorization, as it involves both a failure to verify identity before granting access and a lack of permission checks for specific actions. In terms of the MITRE ATT&CK framework, this behavior is consistent with techniques related to Initial Access or Discovery phases where attackers probe for unprotected endpoints to map out attack surfaces. It also touches upon Defense Evasion if the attacker uses these exposed functions to bypass standard logging or monitoring mechanisms that rely on authenticated user contexts.
Mitigation strategies must prioritize immediate remediation of the authentication gap in the Advanced Forms component. Administrators should ensure that all internal service operations are strictly gated behind robust authentication and authorization checks, verifying both identity and permission levels before executing any logic. Regular security audits and penetration testing focused on API endpoints can help identify similar misconfigurations across other modules. Additionally, implementing rate limiting and web application firewall rules targeting these specific paths can provide a temporary layer of defense against automated exploitation attempts while permanent fixes are deployed by the vendor.
