An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-111997 exists.\n\nAffected packages and fixed versions:\n- ip-address (npm): affected all versions; fixed in 10.7.4\n- ip-address (npm): affected all versions; fixed in 10.7.4\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-2026-111997/ (Markdown: https://insights.sbomify.com/CVE-2026-111997/index.md)","id":"CVE-2026-111997","markdown":"https://insights.sbomify.com/CVE-2026-111997/index.md","name":"CVE-2026-111997","record":{"aliases":["CLEANSTART-2026-TS24569","CLSA-2026-1792486317","CLSA-2026-1792494889","CLSA-2026-1793097494","CLSA-2026-1793098694","CLSA-2026-1793111658","CLSA-2026-1793111838","CLSA-2026-1793180922","CLSA-2026-1793183882","CLSA-2026-1793187941","CLSA-2026-1793207110","DEBIAN-CVE-2026-111997","ECHO-c732-3b7c-69e0","GHSA-rxp7-6hxx-x8q5","MINI-663x-95j7-vvw3","MINI-9938-wrx4-v8g4","MINI-w23w-m4w7-v9jg","UBUNTU-CVE-2026-111997"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript IP address library","requires_auth":"none","summary":"An attacker can cause a denial of service by sending input with many percent characters to the Address6 constructor, leading to high CPU consumption.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":6.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1333","name":"Inefficient Regular Expression Complexity"}],"description":"ip-address before 10.7.4 allows a denial of service (CPU consumption from quadratic complexity, and application stall) via many % characters in input reaching a function call that uses the Address6 constructor.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"ip-address: Address6 matches a zone identifier in quadratic time ahead of its length limit, allowing a single long string to stall the process","id":"CVE-2026-111997","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Vanus 0.8.0 through 0.9.0 Default Admin Credentials via Gateway","id":"CVE-2026-111998"},"packages":[{"ecosystem":"npm","fixed":["10.7.4"],"introduced":["0"],"last_affected":[],"package":"ip-address","purl":null,"source":"GHSA-rxp7-6hxx-x8q5"},{"ecosystem":"npm","fixed":["10.7.4"],"introduced":["0"],"last_affected":[],"package":"ip-address","purl":"pkg:npm/ip-address","source":"GHSA-rxp7-6hxx-x8q5"}],"prev":{"headline":"Soarkey StudentManagement AdminDao.java UserDao.login cleartext storage","id":"CVE-2026-111993"},"products":["ip-address"],"published":"2026-10-18","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-18","vendors":["beaugunderson"]},"summary":"An attacker can cause a denial of service by sending input with many percent characters to the Address6 constructor, leading to high CPU consumption.","url":"https://insights.sbomify.com/CVE-2026-111997/"}
