{"id":"GHSA-gmpm-xp43-f7g6","summary":"Signed to Unsigned Conversion Error in Facebook Hermes","details":"An Integer signedness error in the JavaScript Interpreter in Facebook Hermes prior to commit 2c7af7ec481ceffd0d14ce2d7c045e475fd71dc6 allows attackers to cause a denial of service attack or a potential RCE via crafted JavaScript. Note that this is only exploitable if the application using Hermes permits evaluation of untrusted JavaScript. Hence, most React Native applications are not affected.","aliases":["CVE-2020-1913"],"modified":"2023-11-08T04:02:45.193601Z","published":"2022-05-24T17:27:39Z","database_specific":{"cwe_ids":["CWE-195","CWE-681"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2022-06-24T01:23:39Z","nvd_published_at":"2020-09-09T19:15:00Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2020-1913"},{"type":"WEB","url":"https://github.com/facebook/hermes/commit/2c7af7ec481ceffd0d14ce2d7c045e475fd71dc6"},{"type":"WEB","url":"https://www.facebook.com/security/advisories/cve-2020-1913"}],"affected":[{"package":{"name":"hermes-engine","ecosystem":"npm","purl":"pkg:npm/hermes-engine"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.5.2"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 0.4.3","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/05/GHSA-gmpm-xp43-f7g6/GHSA-gmpm-xp43-f7g6.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
