AI Analysis
Technical Summary
This vulnerability in Node.js HTTP/2 server API causes the server to keep accepting data after sending a GOAWAY frame, which should normally signal the termination of the connection. This behavior can lead to uncontrolled resource consumption (CWE-400), potentially causing denial of service conditions. The issue affects specific versions 22.22.3 and 24.16.0 of Node.js. The CVSS 3.0 base score is 5.3, reflecting a medium impact primarily on availability. No known exploits are reported in the wild, and no official fix or patch has been documented at this time.
Potential Impact
The vulnerability can cause denial of service by exhausting server resources due to continued data acceptance after a GOAWAY frame. There is no impact on confidentiality or integrity. The affected versions are limited to Node.js 22.22.3 and 24.16.0. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, monitor for updates from the Node.js project. No temporary or official fixes have been documented in the provided data.
