CVE-2020-1911 is a critical type confusion vulnerability in Facebook Hermes, specifically affecting versions prior to commit fe52854cdf6725c2eaa9e125995da76e6ceb27da. This flaw allows for potential arbitrary code execution through specially crafted JavaScript objects and prototype chains. Rated 9.8 CRITICAL (CVSSv3.1), it is easily exploitable over the network with low attack complexity, leading to high impacts on confidentiality, integrity, and availability. While not actively exploited or on the KEV catalog, its high FAUCET Risk Score and significant community discussion indicate potential interest, though most React Native applications are not affected due to the requirement for untrusted JavaScript evaluation.
