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-2026-44494 exists.\n\nAffected packages and fixed versions:\n- axios (npm): affected from 1.0.0; fixed in 1.16.0\n- axios (npm): affected from 1.0.0; fixed in 1.16.0\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-2026-44494/ (Markdown: https://insights.sbomify.com/CVE-2026-44494/index.md)","id":"CVE-2026-44494","markdown":"https://insights.sbomify.com/CVE-2026-44494/index.md","name":"CVE-2026-44494","record":{"aliases":["CLEANSTART-2026-MB49894","DEBIAN-CVE-2026-44494","ECHO-a885-7d09-dc48","GHSA-35jp-ww65-95wh","MINI-27f7-p6r6-4q2p","MINI-32wf-rx86-653h","MINI-3cmm-pv2p-fcc3","MINI-7c6c-w8hf-5665","MINI-8584-r7p6-gc29","MINI-8gg8-87pf-6w5w","MINI-9q3p-4vr9-rq5j","MINI-c87v-987w-5hfg","MINI-f8pq-335q-8255","MINI-fq2j-558x-whp8","MINI-hf5c-gpcg-h5c9","MINI-jvc9-5g88-pcrc","MINI-mjp4-fhjj-xjg4","MINI-mq5x-43xq-2h7x","MINI-qfxm-882q-q65w","MINI-qm46-75p6-jv2f","MINI-qw8x-5ccw-3frw","MINI-rf2r-cqcf-m6vj","MINI-rvhm-58p6-pjhh","MINI-v464-vj4x-qpx6","MINI-vp97-6839-6x74","MINI-w2qj-qvfr-4vhj","MINI-w2x6-5rp2-qxw2","MINI-wppv-xwv3-f45g","MINI-xvxc-mjc7-7f3g","ROOT-APP-NPM-CVE-2026-44494","UBUNTU-CVE-2026-44494"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js HTTP client","requires_auth":"none","summary":"Prototype pollution in Axios allows attackers to inject a malicious proxy, enabling full Man-in-the-Middle attacks on HTTP traffic.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"axios","vendor":"axios"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-915","name":"Improperly Controlled Modification of Dynamically-Determined Object Attributes"},{"id":"CWE-441","name":"Unintended Proxy or Intermediary"},{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"Axios is a promise based HTTP client for the browser and Node.js. From 1.0.0 to before 1.16.0, the Axios library is vulnerable to a Prototype Pollution \"Gadget\" attack that allows any Object.prototype pollution in the application's dependency tree to be escalated into a full Man-in-the-Middle (MITM) attack — intercepting, reading, and modifying all HTTP traffic including authentication credentials. The HTTP adapter at lib/adapters/http.js:670 reads config.proxy via standard property access, which traverses the prototype chain. Because proxy is not present in Axios defaults, the merged config object has no own proxy property, making it trivially injectable via prototype pollution. Once injected, setProxy() routes all HTTP requests through the attacker's proxy server. This vulnerability is fixed in 1.16.0.","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":"Axios: Full Man-in-the-Middle via Prototype Pollution Gadget in `config.proxy`","id":"CVE-2026-44494","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"other","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"Axios: Credential Theft and Response Hijacking via Prototype Pollution Gadget in Config Merge","id":"CVE-2026-44495"},"packages":[{"ecosystem":"npm","fixed":["1.16.0"],"introduced":["1.0.0"],"last_affected":[],"package":"axios","purl":null,"source":"GHSA-35jp-ww65-95wh"},{"ecosystem":"npm","fixed":["1.16.0"],"introduced":["1.0.0"],"last_affected":[],"package":"axios","purl":"pkg:npm/axios","source":"GHSA-35jp-ww65-95wh"}],"prev":{"headline":"axios's shouldBypassProxy does not recognize IPv4-mapped IPv6 addresses, allowing NO_PROXY bypass (incomplete fix for CVE-2025-62718)","id":"CVE-2026-44492"},"products":["axios"],"published":"2026-06-11","related":[{"cvss_score":8.6,"headline":"axios's shouldBypassProxy does not recognize IPv4-mapped IPv6 addresses, allowing NO_PROXY bypass (incomplete fix for CVE-2025-62718)","id":"CVE-2026-44492","kev_date_added":null,"published":"2026-06-11"},{"cvss_score":8.3,"headline":"axios before 0.33.0 Prototype Pollution via Node HTTP adapter","id":"CVE-2026-67320","kev_date_added":null,"published":"2026-08-01"},{"cvss_score":8.2,"headline":"Axios: Proxy-Authorization Credential Leak to Origin Server Across HTTP-to-HTTPS Redirect in Axios Node.js HTTP Adapter","id":"CVE-2026-44487","kev_date_added":null,"published":"2026-06-11"},{"cvss_score":7.7,"headline":"Possible SSRF and Credential Leakage via Absolute URL in axios Requests","id":"CVE-2025-27152","kev_date_added":null,"published":"2025-03-07"},{"cvss_score":7.5,"headline":"Axios: Proxy-Authorization header leaks to redirect target when proxy is re-evaluated to direct connection","id":"CVE-2026-44486","kev_date_added":null,"published":"2026-06-11"},{"cvss_score":7.5,"headline":"Axios: Allocation of Resources Without Limits or Throttling in axios","id":"CVE-2026-44488","kev_date_added":null,"published":"2026-06-11"}],"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":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-11","vendors":["axios"]},"summary":"Prototype pollution in Axios allows attackers to inject a malicious proxy, enabling full Man-in-the-Middle attacks on HTTP traffic.","url":"https://insights.sbomify.com/CVE-2026-44494/"}
