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-2026-101910 exists.\n\nAffected packages and fixed versions:\n- ip-address (npm): affected from 10.2.0; fixed in 10.5.1\n- ip-address (npm): affected from 10.2.0; fixed in 10.5.1\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-2026-101910/ (Markdown: https://insights.sbomify.com/CVE-2026-101910/index.md)","id":"CVE-2026-101910","markdown":"https://insights.sbomify.com/CVE-2026-101910/index.md","name":"CVE-2026-101910","record":{"aliases":["CLEANSTART-2026-BJ83966","CLEANSTART-2026-ED95954","CLEANSTART-2026-PU19584","DEBIAN-CVE-2026-101910","ECHO-5e25-ee30-5fe8","GHSA-2vr4-cq9g-pvrc","MINI-32jg-qcvq-fmf4","MINI-3c27-2rj7-wxg5","MINI-4cf4-x853-cf9w","MINI-533f-3hqc-pj9c","MINI-86x6-c48w-pmp9","MINI-892w-v442-jp25","MINI-92j3-3vhm-wfhp","MINI-9cjp-f457-52rp","MINI-gfvf-c377-rqq2","MINI-h5qj-7g9h-v928","MINI-hrm4-xcc4-fqq7","MINI-hxqm-46cc-x52c","MINI-mvv3-6wwm-cxrv","MINI-pv83-r5g9-j35x","MINI-r3pg-9vpc-vq9c","UBUNTU-CVE-2026-101910"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"JavaScript IP address library","requires_auth":"none","summary":"Attackers can bypass network trust boundaries in applications using this library if NAT64 local-use ranges are configured, potentially accessing internal resources.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:H/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"ip-address is a library for parsing and manipulating IPv4 and IPv6 addresses in JavaScript. From 10.2.0 until 10.5.1, the Address6 isPrivate classifier in src/ipv6.ts does not recognize the NAT64 local-use range 64:ff9b:1::/48. Applications that combine isPrivate, isLoopback, and isLinkLocal for a trust-boundary decision can treat an internal IPv4 destination encoded through that range as external. Exploitation depends on a server network using an operator-selected NAT64 prefix within the local-use range. A successful bypass can cross the intended network trust boundary.
