Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
OneUptime is a solution for monitoring and managing online services. Prior to 10.0.23, the telemetry aggregation API accepts user-controlled aggregationType, aggregateColumnName, and aggregationTimestampColumnName parameters and interpolates them directly into ClickHouse SQL queries via the .append() method (documented as "trusted SQL"). There is no allowlist, no parameterized query binding, and no input validation. An authenticated user can inject arbitrary SQL into ClickHouse, enabling full database read (including telemetry data from all tenants), data modification, and potential remote code execution via ClickHouse table functions. This vulnerability is fixed in 10.0.23.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

OneUptime telemetry aggregation API versions prior to 10.0.23 directly interpolate user-controlled parameters (aggregationType, aggregateColumnName, aggregationTimestampColumnName) into ClickHouse SQL queries via .append() without sanitization, parameterized binding, or allowlisting, enabling authenticated users to inject arbitrary SQL for full database access and potential RCE.

MitigationUpgrade to OneUptime version 10.0.23 or later which implements proper input validation and parameterized query handling for the telemetry aggregation API.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed OneUptime version
    Locate the version file, package.json, or docker image tag used in your deployment. Common locations: package.json in the application root, a VERSION file, or the docker container image tag.
    Affected if The installed version is below 10.0.23 (e.g., 10.0.0 through 10.0.22).
  2. Determine if telemetry aggregation API is accessible
    Check your application routing or API endpoint configuration for routes handling telemetry aggregation. Look for endpoints accepting aggregationType, aggregateColumnName, or aggregationTimestampColumnName parameters.
    Affected if The telemetry aggregation API endpoints are exposed and accessible to authenticated users.
  3. Verify ClickHouse is in use
    Check your application configuration files or environment variables for ClickHouse connection settings (e.g., CLICKHOUSE_HOST, CLICKHOUSE_URL, or similar database connection configurations).
    Affected if ClickHouse is configured as a data store for the telemetry system.
  4. Check API authentication configuration
    Review your authentication settings to confirm whether users can authenticate to the telemetry API endpoints.
    Affected if Authenticated users have access to the aggregation API endpoints.

You are affected if running OneUptime version below 10.0.23 with the telemetry aggregation API enabled and accessible to authenticated users, and ClickHouse is used as the underlying database.

Upgrade available Upgrade to 10.0.23 or later
Fixed in 10.0.23
Interim mitigation

Upgrade to OneUptime version 10.0.23 or later which implements proper input validation and parameterized query handling for the telemetry aggregation API.

Recommended fix High confidence

10.0.23

  1. Backup your current OneUptime installation and database before proceeding with the upgrade
  2. Upgrade OneUptime to version 10.0.23 (or the latest version that includes the fix)
  3. After upgrade, verify the telemetry aggregation API endpoint no longer accepts unsanitized SQL in aggregationType, aggregateColumnName, and aggregationTimestampColumnName parameters
  4. Confirm the .append() method is no longer used with user-controlled input in the telemetry aggregation API
