AI-suggested

A patch is available in dd-trace versions 5.131.1 and 6.20.1. Users should upgrade to these fixed versions to remediate the vulnerability. As a temporary workaround, set the environment variable DD_TRACE_OBFUSCATION_QUERY_STRING_REGEXP to the provided fixed regex pattern and restart the application. This mitigates the excessive backtracking issue until an official upgrade can be performed.

Description

A ReDoS vulnerability exists in dd-trace's URL query string obfuscation regex, causing excessive CPU usage when processing crafted inputs. This can stall request processing and lead to denial of service in applications using affected HTTP tracing integrations. The issue affects dd-trace versions >=2.0.0 <5.131.1 and >=6.0.0 <6.20.1. A fixed version is available in 5.131.1 and 6.20.1. A workaround involves setting an updated regex pattern via DD_TRACE_OBFUSCATION_QUERY_STRING_REGEXP and restarting the application.
