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-2026-42044 exists.\n\nAffected packages and fixed versions:\n- axios (npm): affected from 1.0.0; fixed in 1.15.2\n- axios (npm): affected from 1.0.0; fixed in 1.15.2\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-2026-42044/ (Markdown: https://insights.sbomify.com/CVE-2026-42044/index.md)","id":"CVE-2026-42044","markdown":"https://insights.sbomify.com/CVE-2026-42044/index.md","name":"CVE-2026-42044","record":{"aliases":["CLEANSTART-2026-KS96155","CLEANSTART-2026-ZL88777","DEBIAN-CVE-2026-42044","ECHO-c119-30b2-6b3d","GHSA-3w6x-2g7m-8v23","MINI-2ppr-gvg9-p8g3","MINI-42gx-7g7f-w6p9","MINI-4qhw-2vg9-4342","MINI-6597-9458-pfww","MINI-7746-h54q-6pjf","MINI-7fx2-2766-95p5","MINI-8phm-q2rm-vjgm","MINI-8xxg-qmfh-gr82","MINI-fjrq-9v6x-g77m","MINI-h45x-2gwc-m477","MINI-hpg9-4x5v-3h42","MINI-j73g-r65j-f4j2","MINI-jgc9-vq5q-44wj","MINI-mhq2-qm76-7c3f","MINI-p9wp-vxvx-pj67","MINI-q68r-c9qc-wfc8","MINI-qwcf-pqj3-w43r","MINI-r27g-qmh7-fmj2","MINI-vp9h-2p4v-9m2w","MINI-vvj9-hh8m-9cwx","MINI-x565-vwm8-vwhw","ROOT-APP-NPM-CVE-2026-42044","UBUNTU-CVE-2026-42044"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"JavaScript HTTP client","requires_auth":"none","summary":"Prototype pollution allows attackers to tamper with JSON API responses via a polluted parseReviver function, enabling data manipulation and privilege escalation.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"axios","vendor":"axios"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-915","name":"Improperly Controlled Modification of Dynamically-Determined Object Attributes"},{"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 1.15.2, he 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 surgical, invisible modification of all JSON API responses — including privilege escalation, balance manipulation, and authorization bypass. The default transformResponse function at lib/defaults/index.js:124 calls JSON.parse(data, this.parseReviver), where this is the merged config object. Because parseReviver is not present in Axios defaults, not validated by assertOptions, and not subject to any constraints, a polluted Object.prototype.parseReviver function is called for every key-value pair in every JSON response, allowing the attacker to selectively modify individual values while leaving the rest of the response intact. This vulnerability is fixed in 1.15.2.","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: Invisible JSON Response Tampering via Prototype Pollution Gadget in `parseReviver`","id":"CVE-2026-42044","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"deserialization","year":"2026"},"n_packages":2,"n_references":1,"next":{"headline":"LobeHub: Cross-Site Scripting(XSS) escalate to Remote Code Execution(RCE)","id":"CVE-2026-42045"},"packages":[{"ecosystem":"npm","fixed":["1.15.2"],"introduced":["1.0.0"],"last_affected":[],"package":"axios","purl":null,"source":"GHSA-3w6x-2g7m-8v23"},{"ecosystem":"npm","fixed":["1.15.2"],"introduced":["1.0.0"],"last_affected":[],"package":"axios","purl":"pkg:npm/axios","source":"GHSA-3w6x-2g7m-8v23"}],"prev":{"headline":"Axios: Incomplete Fix for CVE-2025-62718 — NO_PROXY Protection Bypassed via RFC 1122 Loopback Subnet (127.0.0.0/8) in Axios 1.15.0","id":"CVE-2026-42043"},"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":"partial"},"state":"PUBLISHED","updated":"2026-09-10","vendors":["axios"]},"summary":"Prototype pollution allows attackers to tamper with JSON API responses via a polluted parseReviver function, enabling data manipulation and privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-42044/"}
