CVE-2026-28381

Local File Read/Write to Potential Privilege Escalation via Snowflake GET/PUT

Published Jun 22, 2026 CVSS 3.1 · 9.6 Critical EPSS < 1% KEV · Not listed
Description
The Snowflake datasource allows for GET/PUT commands, which can allow any user with access to run queries against the data source to read/write files between the local grafana server and the connected Snowflake host.

Analysis

AI-generated

Technical impact

The Snowflake datasource in Grafana implements GET and PUT commands that allow a user who can run queries to read or write files between the local Grafana server and the Snowflake host. An attacker with query permissions can therefore read arbitrary files or overwrite system files on the Grafana server, which can lead to privilege escalation or disruption of services.

Affected Systems

The Grafana Snowflake Datasource component is affected. No specific product versions are listed in the advisory; any installation of the datasource that is still unpatched is considered vulnerable.

Risk and Exploitability

The CVSS score of 9.6 indicates a high severity risk. EPSS is not reported, and the vulnerability is not yet in the CISA KEV catalog. An attacker needs to have the ability to execute queries against the datasource; once that privilege is available, the GET/PUT commands can be used to read or write local files without restriction, making exploitation straightforward for a user with sufficient query access.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update Grafana to a version where the Snowflake datasource restricts or removes GET/PUT file operations.
  • Limit query execution rights to trusted users only, ensuring that only authorized.
  • If an update is not immediately possible, disable or remove the GET/PUT functionality in the datasource configuration to block file read/write operations.
