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.","state":0,"publishedAt":"2026-10-27T20:07:01.195+00:00","modifiedAt":"2026-10-30T19:25:57.583+00:00","affected":[{"ecosystem":"Vendor product","name":"dd-trace-js","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"DataDog\",\n                    \"product\": \"dd-trace-js\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.0.0, < 5.131.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 6.0.0, < 6.20.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://github.com/DataDog/dd-trace-js/security/advisories/GHSA-x94g-w73q-hpcw","https://github.com/DataDog/dd-trace-js/pull/10675","https://github.com/DataDog/dd-trace-js/commit/5eeee790c93036a50549056fc890028cb4c86b1b","https://github.com/DataDog/dd-trace-js/commit/cf4e68a45fa1442c9850f2086c81901258e821b8","https://github.com/DataDog/dd-trace-js/releases/tag/v5.131.1","https://github.com/DataDog/dd-trace-js/releases/tag/v6.20.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116693","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116693","identifiers":["CVE-2026-116693"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
