{"cve":"CVE-2024-52810","nvd":{"published":"2024-11-29T19:15:09.163","modified":"2026-06-17T08:07:40.110","status":"Deferred","description":"@intlify/shared is a shared library for the intlify project. The latest version of @intlify/shared (10.0.4) is vulnerable to Prototype Pollution through the entry function(s) lib.deepCopy. An attacker can supply a payload with Object.prototype setter to introduce or modify properties within the global prototype chain, causing denial of service (DoS) as the minimum consequence. Moreover, the consequences of this vulnerability can escalate to other injection-based attacks, depending on how the library integrates within the application. For instance, if the polluted property propagates to sensitive Node.js APIs (e.g., exec, eval), it could enable an attacker to execute arbitrary commands within the application's context. This issue has been addressed in versions 9.14.2, and 10.0.5. Users are advised to upgrade. There are no known workarounds for this vulnerability.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","score":6.9},"cvss_v3":null,"cwes":["CWE-1321"],"references":["https://github.com/intlify/vue-i18n/commit/9f20909ef8c9232a1072d7818e12ed6d6451024d","https://github.com/intlify/vue-i18n/security/advisories/GHSA-hjwq-mjwj-4x6c"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:57:34.731061660+00:00"},"epss":{"cve":"CVE-2024-52810","score":0.00767,"percentile":0.55525,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-hjwq-mjwj-4x6c","url":"https://osv.dev/vulnerability/GHSA-hjwq-mjwj-4x6c","summary":"@intlify/shared Prototype Pollution vulnerability","modified":"2024-12-02T17:42:18.331443Z","packages":[{"ecosystem":"npm","name":"@intlify/shared","purl":"pkg:npm/%40intlify/shared","ranges":[">=9.7.0 <9.14.2"],"fixed":["9.14.2"]},{"ecosystem":"npm","name":"@intlify/vue-i18n-core","purl":"pkg:npm/%40intlify/vue-i18n-core","ranges":[">=9.7.0 <9.14.2"],"fixed":["9.14.2"]},{"ecosystem":"npm","name":"vue-i18n","purl":"pkg:npm/vue-i18n","ranges":[">=9.7.0 <9.14.2"],"fixed":["9.14.2"]},{"ecosystem":"npm","name":"petite-vue-i18n","purl":"pkg:npm/petite-vue-i18n","ranges":[">=10.0.0 <10.0.5"],"fixed":["10.0.5"]},{"ecosystem":"npm","name":"@intlify/shared","purl":"pkg:npm/%40intlify/shared","ranges":[">=10.0.0 <10.0.5"],"fixed":["10.0.5"]},{"ecosystem":"npm","name":"@intlify/vue-i18n-core","purl":"pkg:npm/%40intlify/vue-i18n-core","ranges":[">=10.0.0 <10.0.5"],"fixed":["10.0.5"]},{"ecosystem":"npm","name":"vue-i18n","purl":"pkg:npm/vue-i18n","ranges":[">=10.0.0 <10.0.5"],"fixed":["10.0.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
