{"id":"CVE-2026-24888","aliases":["GHSA-2cp6-34r9-54xx"],"url":"https://o3.security/vulnerability/CVE-2026-24888","summary":"Maker.js Vulnerable to Unsafe Property Copying in makerjs.extendObject","details":"Maker.js is a 2D vector line drawing and shape modeling for CNC and laser cutters. In versions up to and including 0.19.1, the `makerjs.extendObject` function copies properties from source objects without proper validation, potentially exposing applications to security risks. The function lacks `hasOwnProperty()` checks and does not filter dangerous keys, allowing inherited properties and potentially malicious properties to be copied to target objects. A patch is available in commit 85e0f12bd868974b891601a141974f929dec36b8, which is expected to be part of version 0.19.2.","published":"2026-01-28T21:35:44.030Z","modified":"2026-07-15T01:49:22.538973600Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"makerjs","fixedVersion":"0.19.2"}],"fix":{"url":"https://github.com/microsoft/maker.js/commit/85e0f12bd868974b891601a141974f929dec36b8","label":"microsoft/maker.js@85e0f12"},"references":[{"type":"WEB","url":"https://github.com/microsoft/maker.js/blob/98cffa82a372ff942194c925a12a311253587167/packages/maker.js/src/core/maker.ts#L232-L241"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24888.json"},{"type":"ADVISORY","url":"https://github.com/microsoft/maker.js/security/advisories/GHSA-2cp6-34r9-54xx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24888"},{"type":"FIX","url":"https://github.com/microsoft/maker.js/commit/85e0f12bd868974b891601a141974f929dec36b8"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:22.538973600Z"}}
