CVE-2022-32276
Published: 17 June 2022
Summary
CVE-2022-32276 is a high-severity Improper Authentication (CWE-287) vulnerability in Grafana Grafana. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 2.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2022-32276 is an improper authentication issue (CWE-287) affecting Grafana 8.4.3. It permits unauthenticated access to dashboard snapshot resources through URIs such as /dashboard/snapshot/*?orgId=0, allowing retrieval of content that should require authentication.
An attacker with network access and no credentials can exploit the flaw to read sensitive dashboard data, producing a high confidentiality impact without affecting integrity or availability. The vulnerability carries a CVSS 3.1 base score of 7.5 under the vector AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N.
The vendor states that the behavior is a UI bug rather than a security vulnerability. Public references consist of GitHub issue threads that document the report and vendor response but do not describe patches or configuration mitigations.
The associated EPSS score is currently 0.5082 with a nearly identical peak of 0.5083, indicating sustained moderate exploitation interest after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Detects unauthorized successful logons resulting from improper authentication implementations.
Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.
Security awareness training instructs users on secure authentication practices and avoiding credential compromise.
Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.
Non-repudiation requires strong authentication mechanisms to irrefutably attribute performed actions to specific individuals or processes.
Session content review can reveal authentication bypasses or failures in session establishment.
Review of authentication-related audit records can detect improper authentication mechanisms or bypasses.
Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.
