MITRE ATT&CK
1 technique across 1 tactic: Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Impact | While the CVSS score of 2.2 is low, the risk assessment must account for multiple data points: (1) the vector shows authentication is required (PR:H, high-privilege user), significantly limiting the attack surface; (2) attack complexity is high (AC:H), meaning successful exploitation requires specific conditions; (3) impact is limited to confidentiality with only low-level information disclosure (C:L); (4) no KEV (CISA Known Exploited Vulnerabilities) status is indicated, and no public exploit code is referenced; (5) the defect affects task metadata rather than critical system functions or credentials. This is a genuine but constrained authorization bypass relevant primarily to organizations with multi-tenant or multi-org deployments of runZero where administrative users might maliciously or inadvertently probe cross-organization data. Real-world risk is proportional to the sensitivity of task information and the trustworthiness of high-privilege users within each organization. |
| Exploit ScenarioDerived | A high-privileged administrator within one organization of a multi-tenant runZero deployment could craft API requests or use the platform interface to enumerate or retrieve task information from other organizations within the same instance. While the high authentication barrier (PR:H) and high complexity (AC:H) limit the likelihood, an insider with administrative privileges or a compromised admin account could use this flaw to conduct corporate espionage or gather sensitive information about other organizations' network scanning activities. No public proof-of-concept or active exploitation is known. |

Alert meAnalysisAIv1 – Apr 07, 2026
runZero Platform versions prior to 4.0.260205.0 contain an incorrect authorization flaw that allows authenticated high-privileged users to access task information outside their authorized organization scope via network-based vectors with high complexity. The vulnerability is low-severity (CVSS 2.2) and limited to confidentiality impact (information disclosure), with no public exploit identified at time of analysis.
RemediationAI
Vendor-released patch: upgrade runZero Platform to version 4.0.260205.0 or later. This version includes the authorization controls fix to prevent cross-organization task information disclosure. Organizations should review the official runZero advisory at https://www.runzero.com/advisories/runzero-platform-task-infoleak-cve-2026-5381/ and release notes at https://help.runzero.com/docs/release-notes/#402602050 for deployment guidance. No interim workarounds are documented; patching is the primary remediation path.

Technical ContextAI · show details
The vulnerability stems from CWE-863 (Incorrect Authorization), a category of flaw where an application fails to properly validate that a user has permission to access requested resources. In this case, the runZero Platform's task information retrieval mechanism does not adequately enforce organization-level access controls, allowing high-privileged users authenticated to the system to query or retrieve task data belonging to other organizations. The network-based attack vector combined with high complexity suggests the exploitation requires specific conditions or knowledge of the platform's API/interface, but no special user interaction (UI:N) is needed once authenticated.
