CVE-2026-33939 Handlebars.js has Denial of Service via Malformed Decorator Syntax in Template Compilation
Handlebars provides the power necessary to let users build semantic templates. In versions 4.0.0 through 4.7.8, when a Handlebars template contains decorator syntax referencing an unregistered decorator e.g. n, the compiled template calls lookupPropertydecorators, "n", which returns undefined. Th...
