CVE-2026-82267 in Komodo
Summary
by MITRE • 08/28/2026
Komodo through 2.3.2 discloses internal resource identifiers and writes audit entries before performing permission checks in the /execute and /execute/{variant} handlers. Authenticated users can guess resource names to obtain internal identifiers and insert fraudulent audit log entries misrepresenting privileged operations.

The vulnerability identified in Komodo versions through 2.3.2 represents a critical flaw in access control logic and logging mechanisms, specifically affecting the /execute and /execute/{variant} API handlers. This issue stems from an improper sequence of operations where the system performs security-sensitive actions before validating user permissions. Specifically, the application discloses internal resource identifiers to authenticated users who may not have authorization to access those specific resources. By allowing these identifiers to be returned in responses even when permission checks fail or are bypassed through enumeration techniques, the software exposes sensitive architectural details that can facilitate further attacks against the system infrastructure.
The technical root cause of this vulnerability lies in the order of execution within the request handling pipeline. Instead of verifying whether the authenticated user has the requisite privileges to access a specific resource before processing the request and generating a response, Komodo proceeds with executing the operation or retrieving data first. This design flaw allows attackers who have valid authentication credentials but lack elevated permissions to guess or enumerate internal resource names. Through systematic probing, these users can discover hidden endpoints, configuration details, or sensitive data structures that are not intended for their level of access, effectively bypassing authorization controls through information leakage rather than direct exploitation of a code execution flaw.
Furthermore, the vulnerability extends into the audit logging subsystem, where fraudulent entries are written to logs before permission checks are completed. This behavior creates a significant integrity issue within the security monitoring infrastructure. Attackers can manipulate these log entries to misrepresent privileged operations as if they were performed by legitimate administrators or authorized service accounts. By injecting false records that suggest high-level activities occurred at specific times, an attacker can obscure their actual malicious actions, create confusion for incident responders, and potentially frame other users within the organization. This undermines the reliability of audit trails which are essential for forensic analysis and compliance reporting in regulated environments.
From a classification perspective, this vulnerability aligns with CWE-284 Improper Access Control, as it involves failing to enforce proper restrictions on authenticated users regarding resource access. Additionally, the disclosure of internal identifiers relates closely to CWE-209 Generation of Error Message Containing Sensitive Information, while the manipulation of audit logs corresponds to CWE-778 Insufficient Logging and Monitoring or more specifically CWE-116 Improper Encoding or Escaping of Output for Logs if the injection is active. In terms of offensive tactics, this behavior supports ATT&CK technique T1078 Valid Accounts, as it relies on existing credentials, and potentially T1562 Impair Defenses by disabling or modifying security tools, specifically through log manipulation to evade detection systems that rely on accurate audit data for alerting.
The operational impact of these flaws is substantial, particularly in enterprise environments where Komodo serves as a central component for managing resources or executing commands. The ability to enumerate internal identifiers provides attackers with valuable intelligence about the system's architecture, potentially leading to more targeted attacks against specific services or databases referenced by those identifiers. Simultaneously, the corruption of audit logs compromises the organization’s ability to detect intrusions and maintain accountability. This dual impact means that even if initial access is limited, an attacker can expand their scope through information gathering while simultaneously covering their tracks, making detection and attribution significantly more difficult for security operations teams.
To mitigate these risks, immediate remediation should focus on updating Komodo to a version later than 2.3.2 where the vendor has addressed this logic error. In cases where an upgrade is not immediately feasible, defensive measures must be implemented at the network or application gateway level. Input validation and strict access control checks must be enforced before any resource lookup or log generation occurs. Developers should refactor the handler code to ensure that permission verification happens as the first step in the request processing lifecycle. Additionally, audit logging mechanisms should be decoupled from user-facing response logic to prevent manipulation by unprivileged users. Implementing immutable logging storage and monitoring for anomalies in log timestamps or sources can also help detect attempts to inject fraudulent entries, thereby preserving the integrity of security observability data despite this vulnerability.
