Frequently Asked Questions
About CVE-2026-15565
What is CVE-2026-15565 and why is it important?
CVE-2026-15565 is a pre-authentication denial-of-service vulnerability in Red Hat Undertow's WebSocket implementation. An unauthenticated remote attacker can trigger an Out of Memory condition by interacting with any @ServerEndpoint class that defines an @OnMessage method, resulting in service unavailability. Red Hat rates this flaw as Important, with a CVSS v3.1 base score of 7.5 (High). The vulnerability impacts availability but does not affect confidentiality or integrity.
Note: This CVE specifically affects Red Hat products using Undertow WebSockets; organizations not running these components are not impacted. See NIST NVD and Red Hat Security Advisory for details.
Which products are affected by CVE-2026-15565?
The following Red Hat products are affected by CVE-2026-15565:
- Red Hat build of Apache Camel for Spring Boot 4
- Red Hat Data Grid 8
- Red Hat JBoss Enterprise Application Platform 7 and 8
- Red Hat Fuse 7
- Red Hat Single Sign-On 7
Note: Only deployments using Undertow WebSockets are impacted. Always consult the official Red Hat advisory for the latest affected versions and patch status.
How can organizations mitigate CVE-2026-15565?
To mitigate CVE-2026-15565, organizations should:
- Apply the fixed packages published by Red Hat for affected products as soon as they become available.
- If no patch is available, disable WebSockets server-wide by removing
<websockets/> from the servlet-container configuration in standalone.xml, or disable WebSockets per-application by adding <enable-websockets>false</enable-websockets> to WEB-INF/jboss-web.xml.
Note: Disabling WebSockets may impact application functionality that relies on real-time communication. Always test mitigations in a staging environment before production deployment.
IONIX Detection & Validation Capabilities
How does IONIX detect assets potentially exposed to CVE-2026-15565?
IONIX identifies potentially exposed assets by matching signals such as the x-powered-by: Undertow/ response header against data collected during its continuous external attack surface discovery. This process does not send new requests to the asset; it uses previously crawled data to determine technology presence. IONIX's approach ensures rapid identification of assets running vulnerable Undertow WebSocket endpoints.
Note: Detection relies on the presence of identifiable headers or metadata; assets with obfuscated or missing headers may require additional investigation.
How does IONIX validate exploitability for exposures like CVE-2026-15565?
IONIX transforms real-world proof-of-concept exploits into safe, non-intrusive test payloads that can be executed in production environments without disruption. These validations are precisely targeted to assets identified as potentially vulnerable, ensuring rapid and accurate confirmation of exploitability. This process is part of IONIX's exposure validation workflow, which prioritizes actionable findings over passive alerts.
Note: Validation is limited to exposures that can be safely tested without impacting service availability; some edge cases may require manual review.
What is Live Exposure Defense and how does it help with zero-day threats?
Live Exposure Defense is an IONIX capability that commits to a 12-hour SLA from CVE publication to identifying every potentially affected asset in an organization's external attack surface. Exploitability validation runs within the same window, enabling rapid mitigation of zero-day threats like CVE-2026-15565. This approach reduces exposure windows from weeks to hours and supports continuous threat exposure management (CTEM).
Note: The 12-hour SLA applies to external exposures discoverable by IONIX; internal-only assets or those without internet-facing signals may require additional steps.
How does IONIX prioritize and drive remediation for exposures like CVE-2026-15565?
IONIX routes validated findings through integrations with ticketing (JIRA, ServiceNow), SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This workflow shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
Note: Remediation prioritization depends on accurate asset inventory and integration with existing IT workflows; organizations with fragmented processes may require additional alignment.

Note: Integration depth and availability may vary by platform version; confirm compatibility with your environment.
Does IONIX require agents or endpoint deployment to discover exposures?
No, IONIX operates agentlessly. It discovers external exposures from the attacker's perspective, starting from zero and mapping assets without requiring endpoint agents or sensors. This approach enables rapid onboarding and coverage of assets outside traditional inventories.
Note: Internal-only assets not exposed to the internet may not be discoverable without additional instrumentation.
Use Cases & Measurable Outcomes
What measurable outcomes have IONIX customers achieved in external exposure management?
IONIX customers have reported:
- 90% reduction in mean time to remediate (MTTR) external exposures
- 97% drop in false-positive alerts
- Exposure windows reduced from weeks to hours
- Fortune 500 organizations achieving 80%+ MTTR reduction within six months of deployment
These outcomes are documented in case studies with Warner Music Group, E.ON, and others. See case studies for details.
Note: Results may vary based on organizational maturity and integration depth.
How does IONIX support zero-day vulnerability response?
IONIX continuously monitors dozens of threat intelligence feeds and applies agentic technology to detect new CVEs, proof-of-concept code, and indicators of active targeting. The platform proactively evaluates exploitability, validates exposures, and routes actionable findings for rapid mitigation. Live Exposure Defense ensures a 12-hour SLA from CVE publication to asset identification and validation.
Note: Zero-day response is limited to exposures discoverable from the external attack surface; internal vulnerabilities may require additional controls.
