An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-92599 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- joi (npm): affected from 17.2.0; fixed in 17.13.7\n- joi (npm): affected from 17.2.0; fixed in 17.13.7\n- joi (npm): affected from 18.0.0; fixed in 18.2.6\n- joi (npm): affected from 18.0.0; fixed in 18.2.6\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-92599/ (Markdown: https://insights.sbomify.com/CVE-2026-92599/index.md)","id":"CVE-2026-92599","markdown":"https://insights.sbomify.com/CVE-2026-92599/index.md","name":"CVE-2026-92599","record":{"aliases":["CLSA-2026-1790719586","ECHO-6a04-a4c8-a01f","GHSA-6h2x-m376-mqjq","MINI-3ccg-8x88-gjrr","MINI-442p-5382-wq2q","MINI-48j7-vm2r-cvj5","MINI-4mgc-xgp2-5p8j","MINI-5vq7-ghmv-27x4","MINI-9rr9-mcxr-7w37","MINI-cfm9-wqrv-47w8","MINI-cmfh-jh56-v64r","MINI-gj9r-3982-jvwq","MINI-mr8p-j5fc-f468","MINI-r73j-xc2g-jw58","MINI-rg74-v62x-6jpx","MINI-rjh2-7p67-w8g7","MINI-vg38-cmv6-h92v","MINI-vg8j-grq9-gr2j","MINI-vr8c-r32f-g6cw","MINI-vvq5-mqw3-f6h6","MINI-xg3x-9gjq-v563","ROOT-APP-NPM-CVE-2026-92599","ROOT-APP-NPM-GHSA-6h2x-m376-mqjq"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript validation library","requires_auth":"none","summary":"A remote attacker can cause a denial of service in applications using Joi by submitting a specially crafted ISO date string that triggers excessive regex processing.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.7,"severity":"high","source":"cna","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","version":"4.0"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"joi (npm package `joi`, hapi.js) versions \u003e=17.2.0 \u003c17.13.7 and \u003e=18.0.0 \u003c18.2.6 are vulnerable to regular expression denial of service in the `Joi.string().isoDate()` validation rule. 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.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Joi before 17.13.7 and 18.2.6 ReDoS via isoDate","id":"CVE-2026-92599","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":4,"n_references":2,"next":{"headline":"Guns through 8.3.5 Information Disclosure via Missing Permission Check","id":"CVE-2026-92600"},"packages":[{"ecosystem":"npm","fixed":["17.13.7"],"introduced":["17.2.0"],"last_affected":[],"package":"joi","purl":null,"source":"GHSA-6h2x-m376-mqjq"},{"ecosystem":"npm","fixed":["17.13.7"],"introduced":["17.2.0"],"last_affected":[],"package":"joi","purl":"pkg:npm/joi","source":"GHSA-6h2x-m376-mqjq"},{"ecosystem":"npm","fixed":["18.2.6"],"introduced":["18.0.0"],"last_affected":[],"package":"joi","purl":null,"source":"GHSA-6h2x-m376-mqjq"},{"ecosystem":"npm","fixed":["18.2.6"],"introduced":["18.0.0"],"last_affected":[],"package":"joi","purl":"pkg:npm/joi","source":"GHSA-6h2x-m376-mqjq"}],"prev":{"headline":"Nodemailer before 9.1.0 IDN/Punycode Domain Allow-list Bypass","id":"CVE-2026-92598"},"products":["joi"],"published":"2026-09-16","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-18","vendors":["hapijs"]},"summary":"A remote attacker can cause a denial of service in applications using Joi by submitting a specially crafted ISO date string that triggers excessive regex processing.","url":"https://insights.sbomify.com/CVE-2026-92599/"}
