One of the regular expressions the rule applies to the input is unanchored, so a valid ISO date followed by a long run of fractional-second digits causes the regex engine to restart its search from every position in the string, yielding time proportional to the square of the input length (about 1.4 s for 64 KB of digits and about 22 s for 256 KB). A remote attacker who can supply a string to an isoDate validation can stall the application with a single request. Fixed in 17.13.7 and 18.2.6; as a workaround, cap the length of the string before it reaches joi.","state":0,"publishedAt":"2026-09-16T21:47:03.073+00:00","modifiedAt":"2026-09-18T20:06:43.275+00:00","affected":[{"ecosystem":"Vendor product","name":"joi","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"hapijs\",\n                    \"product\": \"joi\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:npm/joi\",\n                    \"versions\": [\n                        {\n                            \"version\": \"17.2.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"17.13.7\"\n                        },\n                        {\n                            \"version\": \"17.13.7\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"joi","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"hapijs\",\n                    \"product\": \"joi\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"packageURL\": \"pkg:npm/joi\",\n                    \"versions\": [\n                        {\n                            \"version\": \"18.0.0\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"18.2.6\"\n                        },\n                        {\n                            \"version\": \"18.2.6\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\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"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/hapijs/joi/security/advisories/GHSA-6h2x-m376-mqjq","https://www.vulncheck.com/advisories/joi-before-17.13.7-and-18.2.6-redos-via-isodate"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-92599","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-92599","identifiers":["CVE-2026-92599"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
