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-2026-44490 exists.\n\nAffected packages and fixed versions:\n- axios (npm): affected all versions; fixed in 0.32.0\n- axios (npm): affected all versions; fixed in 0.32.0\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-2026-44490/ (Markdown: https://insights.sbomify.com/CVE-2026-44490/index.md)","id":"CVE-2026-44490","markdown":"https://insights.sbomify.com/CVE-2026-44490/index.md","name":"CVE-2026-44490","record":{"aliases":["CLEANSTART-2026-LV37888","CLSA-2026-1785117467","CLSA-2026-1785204471","CLSA-2026-1785291207","CLSA-2026-1785291682","CLSA-2026-1785380880","CLSA-2026-1785380888","CLSA-2026-1785467924","CLSA-2026-1792163995","DEBIAN-CVE-2026-44490","ECHO-c8ae-673f-3aca","GHSA-898c-q2cr-xwhg","MINI-2xmw-9329-x8wv","MINI-39rq-jj7c-fm7v","MINI-48qc-hhf5-ppc5","MINI-532v-xmrh-7m42","MINI-5h72-59r3-r588","MINI-6cg2-vjr5-5qxx","MINI-87wf-fwgh-j2p7","MINI-8xx9-3px6-2936","MINI-9v3p-8v6j-qxq9","MINI-cgf8-j47g-32q3","MINI-cqvf-94xf-vw9c","MINI-g5vh-mr75-p6cv","MINI-g5x7-cjr9-2p2f","MINI-jr78-3qmf-6qpr","MINI-m7w6-p28q-mjqr","MINI-mcrc-g2cm-7j2x","MINI-mp3c-f7mr-m62g","MINI-mp4p-6c5r-2jw4","MINI-p33f-6h67-2fpw","MINI-p895-j32c-288v","MINI-qr6r-42m2-4rcx","MINI-r74r-7jr2-2cpf","MINI-x9mw-mj8w-8x2g","MINI-xcxf-gf6f-xfc8","ROOT-APP-NPM-CVE-2026-44490","UBUNTU-CVE-2026-44490"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript HTTP client","requires_auth":"none","summary":"Prototype pollution in upstream dependencies causes Axios to inject headers or crash requests, requiring an upgrade to fixed versions.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"axios","vendor":"axios"}],"cvss":{"score":4.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"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. Prior to 0.32.0 and 1.16.0, axios exposes two read-side prototype-pollution gadgets. When Object.prototype is polluted by an upstream dependency in the same process (e.g. lodash _.merge / CVE-2018-16487), axios silently picks up the polluted values. (1) lib/utils.js line 406 builds merge()'s accumulator as result = {}, so result[targetKey] (line 414) walks Object.prototype and the polluted bucket's own keys are copied into the merged headers and ride out on the wire. (2) lib/core/mergeConfig.js line 26 builds the hasOwnProperty descriptor as a plain-object literal. Object.defineProperty reads descriptor.get/descriptor.set via the prototype chain, so a polluted Object.prototype.get or Object.prototype.set makes the call throw TypeError synchronously on every axios request. This vulnerability is fixed in 0.32.0 and 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: DoS \u0026 Header Injection via Prototype Pollution Read-Side Gadgets in axios merge functions","id":"CVE-2026-44490","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"other","year":"2026"},"n_packages":4,"n_references":1,"next":{"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"},"packages":[{"ecosystem":"npm","fixed":["0.32.0"],"introduced":["0"],"last_affected":[],"package":"axios","purl":null,"source":"GHSA-898c-q2cr-xwhg"},{"ecosystem":"npm","fixed":["0.32.0"],"introduced":["0"],"last_affected":[],"package":"axios","purl":"pkg:npm/axios","source":"GHSA-898c-q2cr-xwhg"},{"ecosystem":"npm","fixed":["1.16.0"],"introduced":["1.0.0"],"last_affected":[],"package":"axios","purl":null,"source":"GHSA-898c-q2cr-xwhg"},{"ecosystem":"npm","fixed":["1.16.0"],"introduced":["1.0.0"],"last_affected":[],"package":"axios","purl":"pkg:npm/axios","source":"GHSA-898c-q2cr-xwhg"}],"prev":{"headline":"Axios: Proxy-Authorization Header Injection via Prototype Pollution — Incomplete Null-Prototype Fix","id":"CVE-2026-44489"},"products":["axios"],"published":"2026-06-11","related":[{"cvss_score":8.7,"headline":"Axios: Full Man-in-the-Middle via Prototype Pollution Gadget in `config.proxy`","id":"CVE-2026-44494","kev_date_added":null,"published":"2026-06-11"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-06-11","vendors":["axios"]},"summary":"Prototype pollution in upstream dependencies causes Axios to inject headers or crash requests, requiring an upgrade to fixed versions.","url":"https://insights.sbomify.com/CVE-2026-44490/"}
