Threats Tagged 'cve-2026-14199'

Red Hat has released a security advisory addressing multiple high severity vulnerabilities in Red Hat Hardened Images RPMs, including updates to Grafana packages version 12.4.10-0.2.hum1 and 13.1.6-0.2.hum1 for aarch64 and x86_64 architectures. The update is a bug fix and enhancement release that resolves these issues. The advisory covers a range of CVEs including CVE-2026-14199 and others. The update is available and users are advised to apply it as per Red Hat's instructions.

Only self-managed Grafana instances with Auth Proxy authentication and identity caching enabled (sync_ttl greater than zero) are affected. The Auth Proxy cache key concatenated the username and forwarded identity attributes without a delimiter, so distinct identities could collide on one key. An authenticated user who shapes their own attributes to collide with a higher-privileged user's, while that user's cache entry is live, is authenticated as that user, up to Administrator (authentication bypass by spoofing).
