CVE-2026-13719: Alert rules in restricted folders disclosed via the alert rules list API

Noroxi assessment

Priority: Monitor (action score 17/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.23% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Grafana Grafana Enterprise 12.4.12, 13.0.10, 13.1.7; Grafana Grafana OSS 12.4.12, 13.0.10, 13.1.7.

Low priority for now. Upgrade to Grafana Grafana Enterprise 12.4.12, 13.0.10, 13.1.7; Grafana Grafana OSS 12.4.12, 13.0.10, 13.1.7 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
