CVE-2026-9765 in IRM
Summary
by MITRE • 07/24/2026
Note: The CVE and blog post don't exist because we determined this is actually a cloud-only issue.
Access Controls are “Broken” when a user can access resources they are not authorized to access. An attacker can bypass any access control mechanisms in a web application, and gain unauthorized access to resources that are not available with their permissions.
Broken access control can allow attackers to: Access resources only accessible to certain users, thus allowing unauthorized access to data Perform operations on behalf of other users, leading to account takeovers in the worst cases Attempt privilege escalation Attempt to take over an account

Access control vulnerabilities represent one of the most critical security weaknesses in web applications and cloud environments, fundamentally undermining the integrity of authentication and authorization systems. These flaws occur when applications fail to properly enforce access restrictions, allowing unauthorized users to bypass security controls and gain access to resources they should not be permitted to view or modify. The impact extends far beyond simple data exposure, as broken access controls can enable complete account takeovers, privilege escalation, and unauthorized administrative operations. This category of vulnerability directly maps to cwe-284 which defines improper access control as a weakness where software does not properly enforce access restrictions on resources.
The technical implementation of access control failures often stems from inadequate input validation, flawed session management, or missing authorization checks in application code. Attackers can exploit these weaknesses through various techniques including parameter manipulation, direct object reference attacks, or by leveraging authentication bypasses to access restricted functionality. When combined with other vulnerabilities such as insecure deserialization or insufficient logging, broken access controls become even more dangerous as they provide attackers with persistent access to sensitive resources. The operational impact of such vulnerabilities is severe, potentially leading to data breaches, financial losses, and compliance violations that can affect thousands of users.
Cloud environments introduce additional complexity to access control challenges due to the distributed nature of modern applications and the shared responsibility model between cloud providers and customers. In cloud-only scenarios, these vulnerabilities often manifest through misconfigured identity and access management policies, overly permissive role-based access controls, or insecure API endpoints that lack proper authentication mechanisms. The attack surface expands significantly in cloud environments where applications may interact with multiple services, databases, and storage systems, each potentially presenting different access control weaknesses. Organizations must implement comprehensive monitoring solutions to detect unauthorized access attempts and maintain strict access control policies across all cloud resources.
Mitigation strategies should focus on implementing defense-in-depth approaches including proper input validation, secure session management, and robust authorization frameworks. Organizations should adopt principle of least privilege models where users only have access to resources necessary for their specific roles. Regular security testing including penetration testing and automated vulnerability scanning helps identify access control weaknesses before they can be exploited by malicious actors. Additionally implementing proper logging and monitoring systems enables organizations to detect suspicious access patterns and respond quickly to potential security incidents, aligning with attack techniques documented in the attack framework where adversaries often attempt to escalate privileges through access control bypass methods.
