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
An XML external entity (XXE) vulnerability in the /designer/loadReport endpoint of SpringBlade v4.8.0 allows authenticated attackers to execute arbitrary code via injecting a crafted payload.

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 · moderate confidence

SpringBlade v4.8.0 contains an XML External Entity (XXE) injection vulnerability in the /designer/loadReport endpoint. An authenticated attacker can inject malicious XML payloads containing external entity references, allowing the parser to read local files or potentially execute arbitrary code by leveraging the XXE to trigger further attacks.

MitigationDisable external entity processing and DTD processing in the XML parser configuration used by the /designer/loadReport endpoint. Apply vendor-provided patches when available and validate that XML input parsing follows secure defaults.

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 SpringBlade version
    Locate the SpringBlade application JAR/WAR files or check the build configuration (pom.xml, build.gradle) for the version declaration. Typically found in the project root or WEB-INF/lib directory.
    Affected if The installed version matches v4.8.0 or falls within the affected range without a security patch applied.
  2. Verify /designer/loadReport endpoint exists
    Check if the endpoint is accessible by reviewing the application's routing configuration (controller annotations, application.yml routing definitions) or by attempting a HEAD/GET request to /designer/loadReport if the application is running.
    Affected if The endpoint is present and exposed in the application routing.
  3. Inspect XML parser configuration for the loadReport endpoint
    Locate the Java controller handling /designer/loadReport (typically a designer-related controller class). Examine the XML parsing code to determine if DocumentBuilderFactory or similar XML parsers have explicitly disabled external entities via features such as 'DISABLE_DOCTYPE_DECL', 'external-general-entities', and 'external-parameter-entities'.
    Affected if The XML parser configuration does not explicitly set these features to false, meaning external entity processing is enabled.
  4. Review access logs for XXE exploitation attempts
    Search application access logs (typically in logs/ or /var/log/ directories) for requests to /designer/loadReport containing patterns like 'DOCTYPE', 'ENTITY', 'SYSTEM', or 'file://' URIs.
    Affected if Suspicious XXE payload patterns are found in recent requests to the endpoint.

You are affected if SpringBlade v4.8.0 is running with the /designer/loadReport endpoint exposed and the XML parser has not disabled external entity processing.
