A GitHub-reviewed security advisory, not necessarily under active exploitation the way our CISA KEV advisories are, but a real, disclosed vulnerability in an open-source dependency.
Affected packages
Vulnerable: < 0.54.0-beta.3
Patched in 0.54.0-beta.3
Details
What kind of vulnerability is it?
An authenticated user who is only a viewer on project team-a requests GET /api/v1/projects/team-a/dashboards?project=finance-secret (or simply GET /api/v1/datasources?project=finance-secret) and receives the full list of the finance-secret project's dashboards and datasource specifications, despite having no role on that project. This defeats Perses' project-level tenant isolation for all project-scoped read resources.
Who is impacted?
Any authenticated user reads every project's dashboards, datasources, variables across tenants.
Has the problem been patched? What versions should users upgrade to?
None
EPSS, exploit probability
Low0.41%
estimated chance of real-world exploitation in the next 30 days, higher than 35.7% of every CVE FIRST.org scores
Refreshed 11/2/2026, via FIRST.org's EPSS model, not CVSS, this measures likelihood of exploitation, not how severe it would be.
