Technical Analysis

CVE-2026-48619 is a vulnerability in the Node.js HTTP/2 client where a malicious server can send an unlimited number of ORIGIN frames. This can lead to an Out of Memory (OOM) condition on the client side, potentially disrupting client operations. The issue affects multiple supported Node.js release lines including versions >=22.22.3 <22.23.0, >=24.16.0 <24.17.0, >=26.3.0 <26.3.1, and several specific Ubuntu package versions of Node.js 18 and 20. A patch is available to address this issue.

Potential Impact

The vulnerability allows a malicious HTTP/2 server to cause an Out of Memory error on the Node.js HTTP/2 client by sending an unlimited number of ORIGIN frames. This results in denial of service on the client due to memory exhaustion. There is no impact on confidentiality or integrity reported.

Mitigation Recommendations

A patch is available for the affected Node.js versions and Ubuntu packages. Users should update to the fixed versions to remediate this vulnerability. No additional mitigation steps are indicated.
