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-2026-42264 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-2026-42264/ (Markdown: https://insights.sbomify.com/CVE-2026-42264/index.md)","id":"CVE-2026-42264","markdown":"https://insights.sbomify.com/CVE-2026-42264/index.md","name":"CVE-2026-42264","record":{"aliases":["CLEANSTART-2026-IO99141","CLEANSTART-2026-MV85464","DEBIAN-CVE-2026-42264","ECHO-eb29-0852-fa5c","GHSA-q8qp-cvcw-x6jj","MINI-26vr-qrmc-57xc","MINI-2w35-grvg-7f29","MINI-3qq2-9p7f-cjfm","MINI-49p9-9vp9-62h2","MINI-58x3-xm2q-c2vw","MINI-5jrp-g2qv-4r5j","MINI-6rhc-4rjc-8c6q","MINI-74gw-xhhq-wf65","MINI-7mcp-2qx6-h5m5","MINI-gf83-5f3j-rvg9","MINI-gpmh-5hqp-xcvf","MINI-h5j7-243v-h2rh","MINI-h7vr-2gj9-3pp3","MINI-m6vc-gchw-gpc3","MINI-mx9c-2gcq-w5x6","MINI-pwqj-cx8v-8x69","MINI-qh3x-39mv-g456","MINI-rvfh-mvgg-m3mg","MINI-v9w5-cpgp-fh2f","MINI-vf76-j4rv-8fmp","MINI-xf5c-w3x8-rvh5","ROOT-APP-NPM-CVE-2026-42264","UBUNTU-CVE-2026-42264"],"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":"Prototype pollution in Axios allows attackers to inject credentials or hijack HTTP requests by polluting Object.prototype, affecting Node.js applications using the library.","user_interaction":"not_required","vuln_class":"deserialization"},"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-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.
