Red Hat has issued a security advisory for Red Hat Hardened Images RPMs, including an update to the grafana13.2 package (version 13.2.1-0.1.hum1) for aarch64 and x86_64 architectures. This update addresses multiple security vulnerabilities identified by several CVEs. The advisory provides updated RPMs to fix these issues and enhance security. No specific exploit details or active exploitation in the wild have been reported. The update is available and should be applied to affected systems.

This security update for Grafana addresses two vulnerabilities: CVE-2026-33382, which limits the size of the request body at several API endpoints to prevent potential issues, and CVE-2026-8595, which fixes a stored cross-site scripting (XSS) vulnerability in the table panel. Both vulnerabilities have been fixed in this update.

Several Grafana API endpoints, some of them unauthenticated, do not limit the size of the request body before processing it. An attacker can send very large payloads that force excessive memory allocation, potentially exhausting memory and causing a denial of service.
