CVE-2026-48619: CWE-400 Uncontrolled Resource Consumption in nodejs node
A vulnerability in the Node.js HTTP/2 client allows a malicious server to send an unlimited number of ORIGIN frames, potentially causing an Out of Memory (OOM) error on the client. This affects specific versions of Node.js 22, 24, and 26. The issue is categorized as CWE-400 (Uncontrolled Resource Consumption) and has a medium severity rating with a CVSS score of 5.3. No official patch or remediation guidance is currently provided by the vendor.
AI Analysis
Technical Summary
CVE-2026-48619 is a resource exhaustion vulnerability in the Node.js HTTP/2 client implementation. A malicious server can exploit this flaw by sending an unlimited number of ORIGIN frames, which the client processes without adequate limits, leading to excessive memory consumption and potentially causing an Out of Memory error. This affects the Node.js versions 22.22.3, 24.16.0, and 26.3.0. The vulnerability has a CVSS 3.0 base score of 5.3, indicating a medium severity impact focused on availability. There is no vendor advisory or patch available at this time, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation can cause the Node.js HTTP/2 client to consume excessive memory, resulting in an Out of Memory condition that may crash or degrade the availability of applications using the affected Node.js versions. There is no impact on confidentiality or integrity reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider limiting exposure to untrusted HTTP/2 servers or implementing resource usage monitoring and controls at the application or infrastructure level to mitigate potential impact.
