Alpine: multiple grafana packages: security update to 12.4.14-r0

high Tenable Cloud Security Plugin ID 478362

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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).
(CVE-2026-14199)

- When SAML IdP-initiated login is enabled in Grafana Enterprise, the SAML library skips validation of the
InResponseTo field on all SAML responses, including SP-initiated logins. This removes anti-replay
protection, allowing an attacker who obtains a valid signed SAML assertion to replay it and gain a session
as the victim user. Only instances with the allow_idp_initiated SAML setting enabled are affected; this
setting is off by default and Grafana OSS is not affected. (CVE-2026-12704)

- An authenticated user can list alert rules stored in folders they are not allowed to read through the
alert rules API list endpoint. When the set of folders the user may read was empty, the folder restriction
was dropped and every alert rule in the organization was returned. From Grafana 13.1.0, any user can
trigger this with a folder filter. The exposed data is rule configuration; data source credentials are not
exposed. (CVE-2026-13719)

- An Editor can set file-provisioning metadata (the grafana.app/managedBy, grafana.app/managerId and
grafana.app/sourcePath annotations) when creating a dashboard through the dashboard API, because these
fields were stored without an authorization check. The dashboard then appears file-provisioned, and
administrators can no longer update or delete it through Grafana. The impact is limited to the same
organization and no data is exposed. (CVE-2026-13720)

Solution

Update the grafana library and its related packages to version 12.4.14-r0 or later.
