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-2026-42035 exists.\n\nAffected packages and fixed versions:\n- axios (npm): affected all versions; fixed in 0.31.1\n- axios (npm): affected all versions; fixed in 0.31.1\n- axios (npm): affected from 1.0.0; fixed in 1.15.1\n- axios (npm): affected from 1.0.0; fixed in 1.15.1\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-2026-42035/ (Markdown: https://insights.sbomify.com/CVE-2026-42035/index.md)","id":"CVE-2026-42035","markdown":"https://insights.sbomify.com/CVE-2026-42035/index.md","name":"CVE-2026-42035","record":{"aliases":["CLEANSTART-2026-WQ60704","CLEANSTART-2026-XK85655","DEBIAN-CVE-2026-42035","ECHO-cf1c-28f4-2ed2","GHSA-6chq-wfr3-2hj9","MINI-2j76-fpmf-h33x","MINI-4q98-rc7h-99c6","MINI-4x5p-v5wc-3m4m","MINI-6w8v-ffx7-58w2","MINI-6x53-8p3x-372f","MINI-99m3-2g95-28j3","MINI-9m2r-2w4x-j7j5","MINI-c394-mhvx-7p9m","MINI-gvfx-8chf-h277","MINI-h6x8-jxx5-pm37","MINI-j7hv-rx8q-p678","MINI-jjr3-52f7-5jwp","MINI-pvrg-fw5h-cqff","MINI-r4mr-3pmm-46w6","MINI-rx5h-m74h-jxc2","MINI-xc6r-cxmq-wrqh","MINI-xpq3-7jjf-5jpq","MINI-xq46-vmj7-wmpw","MINI-xq5g-hc7g-x6rh","ROOT-APP-NPM-CVE-2026-42035","UBUNTU-CVE-2026-42035"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js HTTP client","requires_auth":"none","summary":"Attackers can inject arbitrary HTTP headers via prototype pollution gadgets, potentially leading to code execution or security bypasses in applications using Axios.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"axios","vendor":"axios"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"},{"id":"CWE-113","name":"Improper Neutralization of CRLF Sequences in HTTP Headers"}],"description":"Axios is a promise based HTTP client for the browser and Node.js. Prior to 1.15.1 and 0.31.1, a prototype pollution gadget exists in the Axios HTTP adapter (lib/adapters/http.js) that allows an attacker to inject arbitrary HTTP headers into outgoing requests. The vulnerability exploits duck-type checking of the data payload, where if Object.prototype is polluted with getHeaders, append, pipe, on, once, and Symbol.toStringTag, Axios misidentifies any plain object payload as a FormData instance and calls the attacker-controlled getHeaders() function, merging the returned headers into the outgoing request. The vulnerable code resides exclusively in lib/adapters/http.js. The prototype pollution source does not need to originate from Axios itself — any prototype pollution primitive in any dependency in the application's dependency tree is sufficient to trigger this gadget. This vulnerability is fixed in 1.15.1 and 0.31.1.","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: Header Injection via Prototype Pollution","id":"CVE-2026-42035","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":4,"n_references":1,"next":{"headline":"Axios: HTTP adapter streamed responses bypass maxContentLength","id":"CVE-2026-42036"},"packages":[{"ecosystem":"npm","fixed":["0.31.1"],"introduced":["0"],"last_affected":[],"package":"axios","purl":null,"source":"GHSA-6chq-wfr3-2hj9"},{"ecosystem":"npm","fixed":["0.31.1"],"introduced":["0"],"last_affected":[],"package":"axios","purl":"pkg:npm/axios","source":"GHSA-6chq-wfr3-2hj9"},{"ecosystem":"npm","fixed":["1.15.1"],"introduced":["1.0.0"],"last_affected":[],"package":"axios","purl":null,"source":"GHSA-6chq-wfr3-2hj9"},{"ecosystem":"npm","fixed":["1.15.1"],"introduced":["1.0.0"],"last_affected":[],"package":"axios","purl":"pkg:npm/axios","source":"GHSA-6chq-wfr3-2hj9"}],"prev":{"headline":"Axios: HTTP adapter streamed uploads bypass maxBodyLength when maxRedirects: 0","id":"CVE-2026-42034"},"products":["axios"],"published":"2026-04-24","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":"total"},"state":"PUBLISHED","updated":"2026-04-25","vendors":["axios"]},"summary":"Attackers can inject arbitrary HTTP headers via prototype pollution gadgets, potentially leading to code execution or security bypasses in applications using Axios.","url":"https://insights.sbomify.com/CVE-2026-42035/"}
