CVE-2026-44902: CWE-755: Improper Handling of Exceptional Conditions in open-telemetry opentelemetry-js
CVE-2026-44902 is a high-severity vulnerability in the OpenTelemetry JavaScript client (opentelemetry-js) versions prior to 0.217.0. The issue arises because the Prometheus metrics endpoint lacks proper error handling for malformed HTTP requests, specifically invalid URIs. This causes an uncaught TypeError that crashes the Node.js process running the exporter. The vulnerability has been fixed in version 0.217.0.
AI Analysis
Technical Summary
The OpenTelemetry JavaScript client (opentelemetry-js) before version 0.217.0 contains an improper handling of exceptional conditions (CWE-755) in its Prometheus exporter. When the metrics endpoint receives an HTTP request with an invalid URI, it triggers an uncaught TypeError due to missing error handling around URL parsing. This results in the termination of the Node.js process hosting the exporter, causing a denial of service. The vulnerability is addressed in version 0.217.0.
Potential Impact
An attacker can cause a denial of service by sending a single malformed HTTP request with an invalid URI to the Prometheus metrics endpoint of the vulnerable OpenTelemetry JS Prometheus exporter. This leads to a crash of the Node.js process running the exporter, impacting availability. There is no impact on confidentiality or integrity.
Mitigation Recommendations
Upgrade opentelemetry-js to version 0.217.0 or later, where this vulnerability is fixed. Since no official patch link or vendor advisory is provided, verify the upgrade from the official OpenTelemetry project sources. Patch status is not yet confirmed via vendor advisory; check the vendor's official channels for the latest remediation guidance.
