Description

The dashboard permissions API does not verify the target dashboard scope and only checks the dashboards.permissions:* action. As a result, a user who has permission management rights on one dashboard can read and modify permissions on other dashboards. This is an organization‑internal privilege escalation.

Analysis

Dashboard permission API fails to validate scope boundaries, allowing authenticated users with permission management rights on any single dashboard to read and modify permissions across all organization dashboards. This privilege escalation affects multi-user dashboard environments where permission isolation is expected. …

Sign in for full analysis, threat intelligence, and remediation guidance.

Remediation

Within 24 hours: inventory all users with dashboards.permissions:* action and audit recent permission changes across all dashboards; disable the permissions API if operationally feasible or restrict it to administrators only. Within 7 days: conduct forensic review of permission modification logs to identify unauthorized changes and remediate any compromised access. …
