Summary
Today we are releasing Grafana 9.2.4. Alongside other bug fixes, this patch release includes moderate severity security fixes for CVE-2022-39306.
We are also releasing security patches for Grafana 8.5.15 to fix these issues.
Release 9.2.4, latest patch, also containing security fix:
Release 8.5.15, only containing security fix:
Appropriate patches have been applied to Grafana Cloud and as always, we closely coordinated with all cloud providers licensed to offer Grafana Pro. They have received early notification under embargo and confirmed that their offerings are secure at the time of this announcement. This is applicable to Amazon Managed Grafana and Azure Managed Grafana as a service offering.
Privilege escalation
Grafana admins can invite other members to the organization they are an admin for. When admins add members to the organization, non existing users get an email invite, existing members are added directly to the organization.
When an invite link is sent, it allows users to sign up with whatever username/email address the user chooses and become a member of the organization.
The CVSS score for this vulnerability is 6.4 Moderate
Impacted versions
All installations for Grafana versions Grafana <=9.x, <8.x

Impact
Vulnerability makes it possible to use the invitation link to sign up with an arbitrary username/email with a malicious intent.
The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths. Typical impact: varies by context: data corruption, logic bypass, or denial of service.
CVE-2022-39306 has a CVSS score of 6.4 (High). The vector is network-reachable, low privileges required, and user interaction required. 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 (8.5.15, 9.2.4); upgrading removes the vulnerable code path.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
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. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
Remediation advice
github.com/grafana/grafana to 8.5.15 or later; github.com/grafana/grafana to 9.2.4 or later

Frequently Asked Questions
- What is CVE-2022-39306? CVE-2022-39306 is a high-severity improper input validation vulnerability in github.com/grafana/grafana (go), affecting versions >= 8.0.0, < 8.5.15. It is fixed in 8.5.15, 9.2.4. The application does not adequately validate input before processing it, allowing unexpected values to reach sensitive code paths.
- How severe is CVE-2022-39306? CVE-2022-39306 has a CVSS score of 6.4 (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.
- Which versions of github.com/grafana/grafana are affected by CVE-2022-39306? github.com/grafana/grafana (go) versions >= 8.0.0, < 8.5.15 is affected.
- Is there a fix for CVE-2022-39306? Yes. CVE-2022-39306 is fixed in 8.5.15, 9.2.4. Upgrade to this version or later.
- Is CVE-2022-39306 exploitable, and should I be worried? Whether CVE-2022-39306 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.

- What actually determines whether CVE-2022-39306 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.
