CVE-2025-1088

Vulnerability

Description CVE-2025-1088 is an improper input validation vulnerability in Grafana. The root cause is that Grafana does not properly validate or limit the length of dashboard titles or panel names. When an excessively long title is rendered in the frontend, it causes Chromium-based browsers to become unresponsive, effectively creating a client-side denial-of-service condition [1][3].

Exploitation

Scenario To exploit this vulnerability, an attacker must have a Grafana account with at least the Editor role, as creating or modifying dashboards requires edit permissions. The attacker can set a very long (likely unicode) string as a dashboard title or panel name. Once a user with lower privileges navigates to the affected dashboard, the browser hangs while trying to render the title, preventing normal use of the Grafana interface [3][4]. The CVSS vector (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L) reflects the need for high privileges and the limited availability impact [3].

Impact

The vulnerability leads to a limited denial of service on the client side. It does not affect the server's availability, data confidentiality, or integrity. The impact is confined to unresponsive browser tabs in Chromium-based browsers for users who view the malicious dashboard [1][3].

Mitigation

The issue is fixed in Grafana version 11.6.2 and later releases. Users running affected versions (before 11.6.2) should upgrade to the patched version as soon as possible. No workarounds have been provided, but restricting dashboard creation privileges can reduce the attack surface [3][4].
