When serializing a specially crafted \"array-like\" object (an object that inherits from `Array.prototype` but has a very large `length` property), the process enters an intensive loop that consumes 100% CPU and hangs indefinitely.\n\n**Who is impacted?**\n\nApplications that use `serialize-javascript` to serialize untrusted or user-controlled objects are at risk. While direct exploitation is difficult, it becomes a high-priority threat if the application is also vulnerable to **Prototype Pollution** or handles untrusted data via **YAML Deserialization**, as these could be used to inject the malicious object.\n\n### Patches\n\n**Has the problem been patched?**\n\nYes, the issue has been patched by replacing `instanceof Array` checks with `Array.isArray()` and using `Object.keys()` for sparse array detection.\n\n**What versions should users upgrade to?**\n\nUsers should upgrade to **`v7.0.5`** or later.\n\n### Workarounds\n\n**Is there a way for users to fix or remediate the vulnerability without upgrading?**\n\nThere is no direct code-level workaround within the library itself. However, users can mitigate the risk by:\n\n* Validating and sanitizing all input before passing it to the `serialize()` function.\n* Ensuring the environment is protected against Prototype Pollution.\n* Upgrading to **`v7.0.5`** as soon as possible.\n\n### Acknowledgements\n\nSerialize JavaScript thanks **Tomer Aberbach** (@TomerAberbach) for discovering and privately disclosing this issue.","references":[{"reference_url":"https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2026-34043.json","reference_id":"","reference_type":"","scores":[{"value":"5.9","scoring_system":"cvssv3","scoring_elements":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"}],"url":"https://access.redhat.com/hydra/rest/securitydata/cve/CVE-2026-34043.json"},{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-34043","reference_id":"","reference_type":"","scores":[{"value":"0.00017","scoring_system":"epss","scoring_elements":"0.04128","published_at":"2026-04-29T12:55:00Z"},{"value":"0.00017","scoring_system":"epss","scoring_elements":"0.04094","published_at":"2026-04-26T12:55:00Z"},{"value":"0.00017","scoring_system":"epss","scoring_elements":"0.04061","published_at":"2026-04-21T12:55:00Z"},{"value":"0.00017","scoring_system":"epss","scoring_elements":"0.04076","published_at":"2026-04-24T12:55:00Z"},{"value":"0.00038","scoring_system":"epss","scoring_elements":"0.11348","published_at":"2026-04-02T12:55:00Z"},{"value":"0.0004","scoring_system":"epss","scoring_elements":"0.12185","published_at":"2026-04-04T12:55:00Z"},{"value":"0.00052","scoring_system":"epss","scoring_elements":"0.16392","published_at":"2026-04-08T12:55:00Z"},{"value":"0.00052","scoring_system":"epss","scoring_elements":"0.16334","published_at":"2026-04-13T12:55:00Z"},{"value":"0.00052","scoring_system":"epss","scoring_elements":"0.16396","published_at":"2026-04-12T12:55:00Z"},{"value":"0.00052","scoring_system":"epss","scoring_elements":"0.16436","published_at":"2026-04-11T12:55:00Z"},{"value":"0.00052","scoring_system":"epss","scoring_elements":"0.16305","published_at":"2026-04-07T12:55:00Z"},{"value":"0.00052","scoring_system":"epss","scoring_elements":"0.16451","published_at":"2026-04-09T12:55:00Z"},{"value":"0.00052","scoring_system":"epss","scoring_elements":"0.16291","published_at":"2026-04-18T12:55:00Z"},{"value":"0.00052","scoring_system":"epss","scoring_elements":"0.16271","published_at":"2026-04-16T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-34043"},{"reference_url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2026-34043","reference_id":"","reference_type":"","scores":[],"url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2026-34043"},{"reference_url":"https://github.com/yahoo/serialize-javascript","reference_id":"","reference_type":"","scores":[{"value":"5.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://github.com/yahoo/serialize-javascript"},{"reference_url":"https://github.com/yahoo/serialize-javascript/commit/f147e90269b58bb6e539cfdf3d0e20d6ad14204b","reference_id":"","reference_type":"","scores":[{"value":"5.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-03-31T13:55:44Z/"}],"url":"https://github.com/yahoo/serialize-javascript/commit/f147e90269b58bb6e539cfdf3d0e20d6ad14204b"},{"reference_url":"https://github.com/yahoo/serialize-javascript/releases/tag/v7.0.5","reference_id":"","reference_type":"","scores":[{"value":"5.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-03-31T13:55:44Z/"}],"url":"https://github.com/yahoo/serialize-javascript/releases/tag/v7.0.5"},{"reference_url":"https://github.com/yahoo/serialize-javascript/security/advisories/GHSA-qj8w-gfj5-8c6v","reference_id":"","reference_type":"","scores":[{"value":"5.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"cvssv3.1_qr","scoring_elements":""},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-03-31T13:55:44Z/"}],"url":"https://github.com/yahoo/serialize-javascript/security/advisories/GHSA-qj8w-gfj5-8c6v"},{"reference_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34043","reference_id":"","reference_type":"","scores":[{"value":"5.9","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"value":"MODERATE","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-34043"},{"reference_url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1132605","reference_id":"1132605","reference_type":"","scores":[],"url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1132605"},{"reference_url":"https://bugzilla.redhat.com/show_bug.cgi?id=245
