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-2026-101911 exists.\n\nAffected packages and fixed versions:\n- ip-address (npm): affected all versions; fixed in 10.7.1\n- ip-address (npm): affected all versions; fixed in 10.7.1\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-2026-101911/ (Markdown: https://insights.sbomify.com/CVE-2026-101911/index.md)","id":"CVE-2026-101911","markdown":"https://insights.sbomify.com/CVE-2026-101911/index.md","name":"CVE-2026-101911","record":{"aliases":["CLEANSTART-2026-FL62325","CLEANSTART-2026-FP38889","CLEANSTART-2026-TU72470","CLEANSTART-2026-WB16925","CLSA-2026-1790862953","CLSA-2026-1790937671","CLSA-2026-1791028139","DEBIAN-CVE-2026-101911","ECHO-0295-6e78-716e","GHSA-h3mg-xc3c-68pw","MINI-22wq-qx3p-j7jf","MINI-24mp-7j7c-869j","MINI-3q9c-8hwh-2rq7","MINI-44fq-jjqh-9q7j","MINI-4794-35qc-4c2j","MINI-4cf8-cp2h-fpmf","MINI-7cwq-76cc-6rf7","MINI-7mw9-997g-mx26","MINI-8f98-q668-29rf","MINI-8p62-v29m-5g43","MINI-cx7m-33h4-2844","MINI-f726-6hg4-vfqc","MINI-fhmp-258q-qg87","MINI-gqcc-p46c-mv72","MINI-gv2c-9377-wvmh","MINI-h6qf-74rp-vrpm","MINI-h8vq-hg3g-4jcm","MINI-j7c9-mjp2-847w","MINI-jcmp-v2hv-9mcj","MINI-jvqw-w5wr-m6qr","MINI-mjpw-85wf-8x9g","MINI-mrvw-27v9-4gwc","MINI-pq92-gv2w-36jh","MINI-qcvr-cxfw-q43r","MINI-qrj7-8r77-23qw","MINI-vmf6-pq6w-8353","MINI-w72w-cphv-3hvq","MINI-wp9j-hcmr-2c98","MINI-x2w7-hc36-456p","MINI-x3g5-w36w-84w6","MINI-xhc8-g587-3hr5","MINI-xr2m-4774-7p89","UBUNTU-CVE-2026-101911"],"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":"Attackers can cause denial of service by passing extremely long strings to the Address6 parser, leading to process stalls or crashes.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","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-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. Prior to 10.7.1, the Address6 constructor, Address6.isValid, and parse code in src/ipv6.ts accept unbounded strings and expand invalid characters through RE_BAD_CHARACTERS into large diagnostics. Material impact occurs only when an application accepts a very large attacker-controlled field and passes it to Address6 parsing without an earlier length bound. Common URL and header limits, and common body-parser defaults, generally constrain the effect; common defaults typically exclude 32 MiB fields. Megabyte-scale fields can cause a synchronous stall and high transient memory use, approximately 16 MiB can trigger an invalid string length exception, and process termination occurs at approximately 32 MiB. The affected entry points include Address6.isValid and construction paths that reach parse.
