Technical Analysis

Red Hat issued a security advisory (RHSA-2026:19134) for Grafana included in Red Hat Enterprise Linux 10, addressing an information disclosure vulnerability (CVE-2026-27877) that could expose data-source passwords through public dashboards. The advisory also includes fixes for two Go language vulnerabilities: a symlink traversal issue in internal/syscall/unix (CVE-2026-32282) and a denial of service via multiple TLS 1.3 key update messages in crypto/tls (CVE-2026-32283). The update is distributed as version 10.2.6-26.el10_2 for Grafana packages across various supported architectures. Red Hat rates the security impact as important and provides updated packages to remediate these issues.

Potential Impact

The primary impact is the potential disclosure of sensitive data-source passwords through public Grafana dashboards, which could lead to unauthorized access to backend data sources. The Go-related vulnerabilities could allow privilege escalation via symlink traversal and denial of service attacks affecting TLS communications. These issues collectively pose a high security risk if unpatched.

Mitigation Recommendations

Red Hat has released updated Grafana packages (version 10.2.6-26.el10_2) for Red Hat Enterprise Linux 10 that address these vulnerabilities. Users should apply the official updates as detailed in the Red Hat advisory RHSA-2026:19134 and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the vendor-provided patches.
