Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-611: Improper Restriction of XML External Entity Reference, where the product processes an xml document that can contain xml entities with uris that resolve to documents outside of the intended sphere of control, causing the product to embed incorrect documents into its output. In Duplicate Advisory, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-3446-6mgw-f79p. This link is maintained to preserve external references. ### Original Description Grav before 2.0.0-beta.2 contains an XML external entity injection vulnerability in SVG file upload processing that allows authenticated attackers to read arbitrary files. The application uses simplexml_load_string without disabling external entity loading, enabling attackers to inject XXE payloads via malicious SVG files to exfiltrate sensitive data.
