{"id":"DEBIAN-CVE-2026-42044","details":"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.","modified":"2026-09-11T18:47:37.185116104Z","published":"2026-04-24T18:16:31.613Z","upstream":["CVE-2026-42044"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-42044"}],"affected":[{"package":{"name":"node-axios","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-axios?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.11.0+dfsg-1","1.12.1+dfsg-1","1.13.1+dfsg-1","1.13.2+dfsg-1","1.14.0+dfsg-1","1.15.0-1","1.15.2-1","1.16.0-1","1.18.0-1","1.19.0-1","1.2.1+dfsg-1","1.2.1+dfsg-1+deb12u1","1.20.0-1","1.5.1+dfsg-1","1.6.2+dfsg-1","1.6.8+dfsg-1","1.6.8+dfsg-2","1.7.3+dfsg-1","1.7.4+dfsg-1","1.7.7+dfsg-1","1.7.9+dfsg-1","1.8.4+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42044.json"}},{"package":{"name":"node-axios","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-axios?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.11.0+dfsg-1","1.12.1+dfsg-1","1.13.1+dfsg-1","1.13.2+dfsg-1","1.14.0+dfsg-1","1.15.0-1","1.15.2-1","1.16.0-1","1.18.0-1","1.19.0-1","1.20.0-1","1.8.4+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42044.json"}},{"package":{"name":"node-axios","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-axios?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.15.2-1"}]}],"versions":["1.11.0+dfsg-1","1.12.1+dfsg-1","1.13.1+dfsg-1","1.13.2+dfsg-1","1.14.0+dfsg-1","1.15.0-1","1.8.4+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42044.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}
