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
In Spring Cloud Data Flow, versions 2.6.x prior to 2.6.5, versions 2.5.x prior 2.5.4, an application is vulnerable to SQL injection when requesting task execution.

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

Spring Cloud Data Flow versions 2.6.x prior to 2.6.5 and 2.5.x prior to 2.5.4 contain a SQL injection vulnerability in the task execution request handler. Attackers can craft malicious input in task execution requests to manipulate SQL queries, potentially exfiltrating or modifying database contents.

MitigationUpgrade Spring Cloud Data Flow to version 2.6.5, 2.5.4, or later. If immediate patching is not possible, implement strict input validation and web application firewall rules to mitigate SQL injection vectors in task execution endpoints.

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 Spring Cloud Data Flow version
    Check the version of Spring Cloud Data Flow running in your environment. This is typically visible in the application startup logs, the about page in the UI, or via the /management/info endpoint if exposed.
    Affected if The installed version is 2.5.0 through 2.5.3, or 2.6.0 through 2.6.4 (anything >= 2.5.0 but < 2.5.4, or >= 2.6.0 but < 2.6.5).
  2. Confirm task execution feature is in use
    Determine if the task execution functionality is enabled and accessible. This includes any REST endpoints or UI options that allow submitting task execution requests, such as /tasks/executions or similar task launch endpoints.
    Affected if Task execution feature is enabled and users can submit task execution requests to the system.
  3. Verify task execution endpoint is network accessible
    Check whether the task execution API endpoints are exposed to network traffic. Review your network configuration, firewall rules, and Spring Cloud Data Flow security settings to determine if these endpoints can be reached by potential attackers.
    Affected if The task execution request handler endpoint is reachable from the network without additional authentication or is accessible to untrusted users.

Your environment is affected if you are running Spring Cloud Data Flow version 2.5.0 to 2.5.3 or 2.6.0 to 2.6.4, and the task execution feature with its REST API is enabled and accessible to users who can submit malicious SQL payloads.
