CVE-2026-27877
When using public dashboards and direct data-sources, all direct data-sources' passwords are exposed despite not being used in dashboards.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.31%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
When using public dashboards and direct data-sources, all direct data-sources' passwords are exposed despite not being used in dashboards. No passwords of proxied data-sources are exposed. We encourage all direct data-sources to be converted to proxied data-sources as far as possible to improve your deployments' security.
