CVE-2026-116693 Details
Description
dd-trace is the Datadog APM client for Node.js. From 2.0.0 until 5.131.1 and 6.20.1, the default DD_TRACE_OBFUSCATION_QUERY_STRING_REGEXP can perform excessive backtracking on attacker-controlled URL query strings. The expression is applied synchronously while recording HTTP URL metadata, allowing a crafted request to consume excessive CPU, stall request processing, and make the instrumented application unavailable. This issue is fixed in versions 5.131.1 and 6.20.1.
A denial-of-service vulnerability has been identified in the Datadog APM client for Node.js, specifically in the dd-trace package versions 2.0.0 through 5.131.0 and 6.0.0 through 6.20.1. The issue arises from the default query string obfuscation regular expression, which can be exploited to cause excessive backtracking on attacker-controlled URL query strings. This backtracking is processed synchronously while recording HTTP URL metadata, allowing crafted requests to consume significant CPU resources, disrupt request processing, and render the application unavailable. The vulnerability is present in the HTTP tracing integrations that include query strings in the URL span tags.
Users can upgrade to dd-trace versions 5.131.1 or 6.20.1, both of which include the necessary fix. After upgrading, the application should be restarted.
