CVE-2026-82279 in HyperDX
Summary
by MITRE • 08/28/2026
HyperDX through 1.10.1 fails to enforce role-based access controls in team management endpoints, allowing any team member to perform administrative actions. Attackers can delete team members including owners, rotate API keys, and rename teams by sending requests to PATCH /team/apiKey, PATCH /team/name, and DELETE /team/member endpoints.

The vulnerability identified in HyperDX versions through 1.10.1 represents a critical failure in role-based access control mechanisms within the application's team management subsystem. This flaw allows any authenticated user who is a member of a team to execute administrative actions that should be restricted exclusively to users with elevated privileges, such as team owners or administrators. The core technical issue lies in the server-side validation logic for specific API endpoints, which fails to verify whether the requesting user possesses the necessary permissions before processing state-changing requests. This lack of proper authorization checks creates a direct path for privilege escalation and unauthorized modification of critical team configurations.
The operational impact of this vulnerability is severe due to the breadth of actions an attacker can perform once they have gained access as a standard team member. By exploiting endpoints such as PATCH /team/apiKey, PATCH /team/name, and DELETE /team/member, an adversary can disrupt service availability and compromise security posture without needing initial high-level credentials. Specifically, the ability to rotate API keys allows an attacker to invalidate legitimate authentication tokens, potentially locking out existing users or forcing a reset that may expose sensitive configuration details during the renewal process. Furthermore, renaming teams can cause confusion in logging aggregation systems and monitoring dashboards, leading to operational blind spots where security events might be misattributed or missed entirely.
The most damaging aspect of this flaw is the capability to delete team members, including those with owner-level privileges. By removing owners from a team, an attacker effectively seizes control over the remaining infrastructure associated with that team. This action can lead to complete loss of administrative oversight, as no authorized personnel remain to manage access policies or respond to security incidents. The removal of other members further isolates the attack surface and prevents collaborative remediation efforts by legitimate stakeholders. Such actions undermine the fundamental principle of least privilege and demonstrate a significant gap in identity and access management protocols within the application architecture.
From a classification perspective, this vulnerability aligns with CWE-269, which denotes Improper Privilege Control, as it involves an actor obtaining privileges that they are not explicitly granted by the system's security model. Additionally, the exploitation technique maps to MITRE ATT&CK tactic T1078, specifically Valid Accounts and potentially T1484 for Domain Policy Modification if team settings influence broader organizational policies. The attack vector is classified as remote with low complexity, requiring only valid authentication credentials for a standard user account, which makes it highly feasible for malicious insiders or external attackers who have compromised lower-level accounts through phishing or credential stuffing attacks.
Mitigation strategies must prioritize immediate patching to the latest version of HyperDX where these access control checks are properly enforced. In environments where upgrading is not immediately possible, network segmentation and strict firewall rules should be applied to restrict access to team management endpoints only from trusted administrative interfaces if such separation exists. Additionally, implementing robust logging and monitoring for changes to API keys, team names, and member lists can aid in rapid detection of unauthorized modifications. Security teams should also review existing user roles and permissions to ensure that no unnecessary broad-access policies are in place while waiting for the software update. Regular audits of access control logic across all administrative endpoints are recommended to prevent similar vulnerabilities from persisting in other parts of the application.
