CVE-2019-20922 1 Handlebarsjs 1 Handlebars 2021-07-21 7.8 HIGH 7.5 HIGH
Handlebars before 4.4.5 allows Regular Expression Denial of Service (ReDoS) because of eager matching. The parser may be forced into an endless loop while processing crafted templates. This may allow attackers to exhaust system resources.
CVE-2019-20920 1 Handlebarsjs 1 Handlebars 2020-10-15 6.8 MEDIUM 8.1 HIGH
Handlebars before 3.0.8 and 4.x before 4.5.3 is vulnerable to Arbitrary Code Execution. The lookup helper fails to properly validate templates, allowing attackers to submit templates that execute arbitrary JavaScript. This can be used to run arbitrary code on a server processing Handlebars templates or in a victim's browser (effectively serving as XSS).
