{"id":"CVE-2026-116693","summary":"dd-trace: ReDOS in URL query string obfuscation","details":"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.","aliases":["GHSA-x94g-w73q-hpcw"],"modified":"2026-10-28T10:45:42.561895992Z","published":"2026-10-27T20:07:01.195Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/116xxx/CVE-2026-116693.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-1333"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/116xxx/CVE-2026-116693.json"},{"type":"FIX","url":"https://github.com/DataDog/dd-trace-js/commit/5eeee790c93036a50549056fc890028cb4c86b1b"},{"type":"FIX","url":"https://github.com/DataDog/dd-trace-js/commit/cf4e68a45fa1442c9850f2086c81901258e821b8"},{"type":"FIX","url":"https://github.com/DataDog/dd-trace-js/pull/10675"},{"type":"WEB","url":"https://github.com/DataDog/dd-trace-js/releases/tag/v5.131.1"},{"type":"WEB","url":"https://github.com/DataDog/dd-trace-js/releases/tag/v6.20.1"},{"type":"ADVISORY","url":"https://github.com/DataDog/dd-trace-js/security/advisories/GHSA-x94g-w73q-hpcw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-116693"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/datadog/dd-trace-js","events":[{"introduced":"c2687fe24fb32ed4ff1df2c7dbf195678584b03f"},{"fixed":"2f04bd36d5bb876d8e7cf9c69ed4bd8f9e80b076"},{"introduced":"4f3d8bb4eafec0c8db46042ab9709773ca4cb303"},{"fixed":"f3517f33400a7e5cce8f1c691fd54355ed63c206"},{"fixed":"5eeee790c93036a50549056fc890028cb4c86b1b"},{"fixed":"cf4e68a45fa1442c9850f2086c81901258e821b8"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"2.0.0"},{"fixed":"5.131.1"}],"source":"AFFECTED_FIELD","strategy":"StringRangeExpression"},{"range":[{"introduced":"6.0.0"},{"fixed":"6.20.1"}],"source":"AFFECTED_FIELD","strategy":"StringRangeExpression"},{"range":[{"fixed":"5eeee790c93036a50549056fc890028cb4c86b1b"}],"source":"REFERENCES_COMMIT"},{"range":[{"fixed":"cf4e68a45fa1442c9850f2086c81901258e821b8"}],"source":"REFERENCES_COMMIT"},{"original_tag":"v5.131.1","range":[{"fixed":"2f04bd36d5bb876d8e7cf9c69ed4bd8f9e80b076"}],"source":"REFERENCES_TAG"},{"source":"REFERENCES_TAG","original_tag":"v6.20.1","range":[{"fixed":"f3517f33400a7e5cce8f1c691fd54355ed63c206"}]}]}}],"versions":["v6.20.0","v6.19.0","v6.18.0","v6.17.0","v6.16.0","v6.15.0","v6.14.0","v6.13.0","v6.12.0","v6.11.0","v6.10.0","v6.9.0","v6.8.0","v6.7.0","v6.6.0","v6.5.0","v6.4.0","v6.3.0","v6.2.0","v6.1.0","v6.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-116693.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"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"}]}
