DescriptionCVE.org

OpenPanel before 2.3.0 contains a cross-tenant broken object level authorization vulnerability in the report.getLayouts and report.resetLayout tRPC procedures that fail to scope dashboard queries to the caller's project. Authenticated attackers can supply their own projectId with a victim organization's guessable dashboardId to read confidential report definitions or permanently delete dashboard layouts across tenant boundaries.

AnalysisAI

Cross-tenant broken object level authorization (BOLA) in OpenPanel before 2.3.0 exposes confidential report definitions and enables permanent destruction of dashboard layouts across tenant boundaries. The report.getLayouts and report.resetLayout tRPC procedures accept caller-supplied projectId values without verifying tenant ownership, allowing any authenticated user to target a victim organization's dashboards by supplying guessable dashboardId values. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a valid OpenPanel account in any tenant - authentication cannot be bypassed. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 5.3 (Medium) is broadly appropriate given the authentication requirement (PR:L) and the limited per-object confidentiality and integrity impacts (VC:L/VI:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade to OpenPanel 2.3.0 or later, which patches both tRPC procedures to enforce tenant-scoped ownership validation before resolving dashboard objects. … Detailed patch versions, workarounds, and compensating controls in full report.
