Why This Update Matters for Enterprises

RabbitMQ is a mission-critical message broker used in high-availability systems. Unpatched XSS flaws could compromise:

• Admin dashboards (via malicious error messages).

• API integrations (if error outputs are rendered in web UIs).

• Compliance postures (e.g., GDPR, HIPAA for logged errors).

Pro Tip: Pair this update with a web application firewall (WAF) to mitigate zero-day risks.
