Description PRE-NVD

Disclosed via GitHub release of nodejs/node. NVD scoring and full description are pending.

AnalysisAI

Denial-of-service exposure in Node.js HTTP/2 handling stems from integration defects with the nghttp2 library, addressed in the Node.js 24.17.0 'Krypton' LTS security release on 2026-06-18. Remote, unauthenticated attackers (per CVSS:3.0/PR:N/AV:N) can trigger availability degradation through crafted HTTP/2 traffic exploiting the flawed nghttp2 integration layer. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the target to be running Node.js 24.x prior to 24.17.0 with HTTP/2 enabled - which is opt-in via the http2 module or server configuration, not the default for basic HTTP/1.1 servers. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS base score of 5.3 (Medium) with A:L reflects a genuine but bounded risk: availability impact is rated Low rather than High, suggesting partial or transient disruption rather than complete service crash. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker sends a sequence of crafted HTTP/2 frames to a publicly accessible Node.js 24.x server, triggering the integration defect between Node.js and the bundled nghttp2 library, causing degraded availability - such as elevated memory consumption, processing stalls, or partial request handling failures - without requiring authentication or user interaction. Because AC:L and PR:N, this scenario requires no special setup beyond a reachable HTTP/2 endpoint. …
Remediation Upgrade to Node.js 24.17.0 ('Krypton' LTS) or later, available at https://github.com/nodejs/node/releases/tag/v24.17.0 and detailed in the Node.js security advisory at https://nodejs.org/en/blog/vulnerability/june-2026-security-releases. … Detailed patch versions, workarounds, and compensating controls in full report.
