DescriptionCVE.org

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.

AnalysisAI

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. No patch is currently available.

Technical ContextAI

Classified as CWE-863 (Incorrect Authorization). 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.

RemediationAI

Monitor vendor advisories for a patch. Restrict network access to the affected service where possible.
