CVE-2026-19204: Technical Details & Mitigation

What is CVE-2026-19204 and how does it affect Eclipse Jetty WebSocket?

CVE-2026-19204 is a denial-of-service vulnerability in Eclipse Jetty's WebSocket implementation. It is caused by uncontrolled resource allocation when handling malformed frames. A remote, unauthenticated attacker can send a WebSocket frame with an unknown opcode and an extremely large declared payload length, forcing the server to attempt a massive memory allocation. This can exhaust the JVM heap and crash the affected service. The vulnerability affects Jetty versions 10.0.0–10.0.31, 11.0.0–11.0.31, 12.0.0–12.0.37, and 12.1.0–12.1.11. The issue carries a HIGH severity rating (CVSS v4.0 Base Score: 8.7). Note: No confidentiality or integrity impact is reported; the primary risk is application unavailability due to memory exhaustion.

What mitigation steps are recommended for CVE-2026-19204?

The recommended mitigation is to upgrade to Jetty 12.0.38 or Jetty 12.1.12, which include public fixes for this issue. For Jetty 10.x and 11.x, which have reached end-of-life for public releases, organizations should migrate to a supported 12.x release or obtain a fix through a commercial extended-support channel. If patching is delayed, disable or restrict WebSocket auto-fragmentation where feasible, place WebSocket endpoints behind a proxy/load balancer or WAF capable of enforcing frame size and opcode validation, and monitor JVM heap usage for anomalous spikes correlated with WebSocket traffic. Note: Organizations unable to migrate from unsupported Jetty versions may remain exposed until a patch is applied.

How does IONIX identify assets potentially affected by CVE-2026-19204?

IONIX identifies potentially affected assets by matching HTTP response headers containing the value 'Jetty', optionally followed by a version in parentheses (e.g., Jetty(12.1.11)), against data collected during its external asset discovery crawl. This process does not send additional requests beyond the initial crawl, ensuring non-intrusive detection. Note: Detection accuracy depends on the presence of version information in HTTP headers; assets with obfuscated or missing headers may require additional investigation.

IONIX Platform Capabilities for Zero-Day and CVE Response

How does IONIX detect and validate zero-day vulnerabilities like CVE-2026-19204?

New CVE Detected

CVE-2026-19204 – Denial of Service (Memory Exhaustion) – Eclipse Jetty WebSocket (10.0.0–10.0.31, 11

Be the first to know when new zero-days emerge:

Summary

CVE-2026-19204 is a denial-of-service vulnerability in Eclipse Jetty’s WebSocket implementation, caused by uncontrolled resource allocation when handling malformed frames. A remote, unauthenticated attacker can send a WebSocket frame with an unknown opcode and an extremely large declared payload length to force the server to attempt a massive memory allocation, potentially exhausting the JVM heap and crashing the affected service. The issue carries a HIGH severity rating.

Technical details

  • Root cause: When auto-fragmentation is enabled, Jetty allocates a buffer for the declared payload size before it validates the frame’s opcode. Unknown opcodes bypass the standard maximum frame size checks that would normally reject an oversized frame.
  • Trigger condition: A WebSocket connection must be established to an affected Jetty endpoint with auto-fragmentation enabled; the attacker then sends a frame using a non-standard/unknown opcode along with an inflated payload length field.
  • Attack vector: Network — no authentication or user interaction required.
  • Impact: Excessive memory allocation can exhaust available JVM heap, leading to denial of service (application unavailability) for the affected Jetty instance. No confidentiality or integrity impact is reported.
  • Weaknesses: CWE-770 (Allocation of Resources Without Limits or Throttling) and CWE-789 (Memory Allocation with Excessive Size Value).

Affected software

  • Eclipse Jetty 12.1.0 through 12.1.11
  • Eclipse Jetty 12.0.0 through 12.0.37
  • Eclipse Jetty 11.0.0 through 11.0.31
  • Eclipse Jetty 10.0.0 through 10.0.31

Severity

  • CVSS v4.0 Base Score: 8.7 (High)
  • Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N

Mitigation and recommended actions

  • Immediate: Upgrade to Jetty 12.0.38 or Jetty 12.1.12, which include public fixes for this issue.
  • Note on 10.x/11.x: These lines reached end-of-life for public releases (Maven Central publication for the 9.x/10.x/11.x lines stopped January 1, 2026); no public patched build beyond 10.0.31/11.0.31 exists. Organizations still running Jetty 10.x or 11.x should migrate to a supported 12.x release, or obtain a fix through a commercial extended-support channel if migration is not immediately possible.
  • If patching is delayed: Disable or restrict WebSocket auto-fragmentation where feasible, and place WebSocket endpoints behind a proxy/load balancer or WAF capable of enforcing frame size and opcode validation, and monitor JVM heap usage for anomalous spikes correlated with WebSocket traffic.

How IONIX identifies potentially affected assets

IONIX matches the following signals against data already collected when it crawled the asset; identifying the technology sends no request beyond that crawl.

  • HTTP response header Server: value containing Jetty, optionally followed by a version in parentheses, e.g. Jetty(12.1.11)
