CVE-2026-7778 Overview
CVE-2026-7778 is an improper privilege management vulnerability [CWE-269] in the runZero Platform. The flaw allows an authenticated user to view dashboard configurations belonging to organizations outside their authorized scope. The issue affects multi-tenant deployments where organizational boundaries are expected to enforce data isolation.
runZero resolved the vulnerability in version v4.0.260416.0 of the runZero Platform. The CVSS vector indicates network-based exploitation with low privileges required and a scope change, leading to limited confidentiality impact. No integrity or availability impact has been identified.
Critical Impact
Authenticated users could read dashboard configuration data from organizations they were not authorized to access, breaking multi-tenant isolation in the runZero Platform.
Affected Products
- runZero Platform versions prior to v4.0.260416.0
- Multi-organization runZero deployments
- Hosted and self-hosted runZero Platform instances

Technical Details for CVE-2026-7778
Vulnerability Analysis
The runZero Platform supports multi-organization deployments where dashboards and configurations are scoped to specific organizational boundaries. The vulnerability stems from missing or insufficient authorization checks when retrieving dashboard configuration data. An authenticated user with low privileges could request dashboard configurations associated with organizations outside their authorized scope.
The vulnerability is classified as Improper Privilege Management [CWE-269]. It represents a horizontal authorization failure where access controls validate authentication but fail to enforce the organizational scope tied to the requesting principal. The scope change (S:C) indicates the issue affects resources beyond the security authority of the originally authenticated context.
EPSS scoring data lists exploitation probability at 0.025%, reflecting low predicted exploitation activity. No public exploit code or proof-of-concept has been published.
Root Cause
The root cause is missing tenant-scope enforcement in the dashboard configuration retrieval path. Authorization logic verified the requester held a valid session but did not verify the requested dashboard belonged to an organization within the requester's authorized scope. This pattern is a recurring weakness in multi-tenant SaaS architectures where object-level authorization is decoupled from authentication.
Attack Vector
Exploitation requires network access to the runZero Platform and valid authenticated credentials within at least one organization. An attacker with low-privilege access could enumerate or directly request dashboard identifiers belonging to unrelated organizations. The platform would return dashboard configuration content without verifying tenant boundaries, exposing layout, query definitions, and asset filter logic configured by other customers.
The vulnerability does not permit modification of remote dashboards, account takeover, or service disruption. Disclosure is limited to dashboard configuration metadata. See the runZero Security Advisory for vendor analysis.
Detection Methods for CVE-2026-7778
Indicators of Compromise
- Audit log entries showing dashboard configuration reads where the requesting user's organization does not match the dashboard's owning organization.
- Unusual API request patterns enumerating sequential or non-sequential dashboard identifiers from a single authenticated session.
- Authentication events from low-privilege accounts immediately followed by atypical dashboard configuration retrievals.
Detection Strategies
- Review runZero Platform audit logs for dashboard access events and correlate the requesting user's organization with the dashboard's organizational scope.
- Alert on API consumers issuing repeated dashboard configuration requests across multiple distinct dashboard identifiers within short time windows.
- Compare current platform version against v4.0.260416.0 to confirm patch status.
Monitoring Recommendations
- Forward runZero Platform audit and access logs to a centralized logging or SIEM platform for retention and analysis.
- Establish a baseline of typical dashboard access volume per user and alert on deviations.
- Track service account and API token usage for behaviors consistent with cross-tenant enumeration.
How to Mitigate CVE-2026-7778
Immediate Actions Required
- Upgrade the runZero Platform to version v4.0.260416.0 or later as documented in the runZero Release Notes.
- Audit dashboard configurations for sensitive query logic, asset filters, or naming conventions that may have been exposed prior to patching.
- Review user and API token inventory and revoke credentials that are no longer required.
Patch Information
runZero released the fix in runZero Platform version v4.0.260416.0. Hosted runZero deployments are updated by the vendor. Self-hosted customers should plan an upgrade to the patched release as outlined in the official release notes.
Workarounds
- No vendor-supplied workaround is available; upgrading to v4.0.260416.0 is the recommended remediation.
- Restrict runZero Platform access to trusted networks and enforce least-privilege role assignments to reduce the population of accounts capable of triggering the issue.
- Rotate API tokens and review organization membership for unused or over-privileged accounts.
