CVE-2020-1913 (GCVE-0-2020-1913)

Vulnerability from cvelistv5 – Published: 2020-09-09 19:00 – Updated: 2024-08-04 06:53

Summary

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.

Severity

No CVSS data available.
