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
Bernd Bestel grocy v4.6.0 was discovered to contain a SQL injection vulnerability in the product-group parameter at /stockreports/spendings. This vulnerability allows attackers to access sensitive database information via a crafted SQL statement.

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

A SQL injection vulnerability in grocy v4.6.0 allows remote attackers to inject malicious SQL code through the product-group parameter at the /stockreports/spendings endpoint, potentially exposing sensitive database information.

MitigationApply vendor patch or upgrade to a fixed version; as a compensating control, implement parameterized queries and input validation on the product-group parameter.

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 grocy installation version
    Locate the grocy installation and check its version. Common methods: check package.json, composer.json, or the application's internal version file (often in /data or /config). If running as a container, check the image tag. For docker deployments, run 'docker images' and inspect labels.
    Affected if version is 4.6.0 or falls within an unpatched range and cannot be determined (unknown version)
  2. Verify /stockreports/spendings endpoint accessibility
    Confirm the endpoint is reachable in your environment. Check web server routing configuration (nginx/apache), reverse proxy settings, or firewall rules that expose this path. Verify authentication requirements for this route.
    Affected if the /stockreports/spendings endpoint is accessible to untrusted users or without proper authentication controls
  3. Confirm product-group parameter processing
    Review application logs or code to identify how the product-group parameter is handled at the /stockreports/spendings endpoint. Check if raw parameter values are passed to SQL queries without parameterized query implementation.
    Affected if the product-group parameter is processed through direct string concatenation into SQL queries rather than using parameterized queries
  4. Check for existing input validation
    Inspect the application's input validation layer for the stockreports module. Look for sanitization, allowlist validation, or web application firewall rules targeting the product-group parameter.
    Affected if no input validation, sanitization, or compensating controls exist for the product-group parameter at this endpoint

You are affected if your grocy version is 4.6.0 or unpatched, the /stockreports/spendings endpoint is exposed, and the product-group parameter accepts unsanitized input that gets passed to SQL queries.
