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
Due to missing validation of XML input, an unauthenticated attacker could send malicious input to an endpoint which leads to XML Entity Expansion attack. This causes limited impact on availability of the application.

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

This is an XML External Entity (XXE) vulnerability caused by missing validation of XML input. An unauthenticated attacker can send malicious XML with entity expansion (e.g., billion laughs attack) to an endpoint, causing resource exhaustion and limited availability impact.

MitigationDisable external entity processing and DTD parsing in XML parsers. Implement proper XML input validation and sanitization. Use secure XML parser configurations that prevent entity expansion.

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 XML input endpoints
    Review application logs, API documentation, or network traffic to find endpoints accepting XML data (Content-Type: application/xml, text/xml, or XML in request body)
    Affected if The system accepts unauthenticated XML input at any endpoint without documented XXE protections
  2. Examine XML parser configuration
    Locate XML parser initialization code or configuration files and check for settings controlling external entity processing such as 'external-general-entities', 'external-parameter-entities', or 'allow-dtd'
    Affected if External entity processing or DTD parsing is explicitly enabled or defaults to enabled in the XML parser
  3. Verify entity expansion protection
    Inspect XML parser settings for protections against billion laughs attack, such as entity expansion limits, XXE disable flags, or FEATURE_SECURE_PROCESSING
    Affected if The XML parser lacks entity expansion limits or explicit XXE protection settings and accepts untrusted XML input
  4. Check XML input validation
    Review application code that handles XML requests to determine if schema validation (XSD) or input sanitization is performed before parsing
    Affected if XML input is parsed without prior validation against a schema or sanitization of potentially malicious entity declarations

A system is affected by this CVE if it accepts unauthenticated XML input and its XML parser has external entities and DTD processing enabled without entity expansion limits or input validation.
