Handlebars: JavaScript Injection via AST Type Confusion in compile (bypass of CVE-2026-33937)

Summary Handlebars.compile and Handlebars.precompile accept a pre-parsed AST as well as a template string. Handlebars 4.7.9 added validation for such ASTs. It only checks values on PathExpression, NumberLiteral and BooleanLiteral nodes, and the compiler still writes several other AST values into...

Handlebars: JavaScript Injection via Own Property Check Bypass

Summary Handlebars can expose the Function constructor despite its prototype-access deny list. When a template reaches Function.prototype, its own constructor property is returned before the deny list is checked. An attacker who can render a controlled template with allowProtoMethodsByDefault: tr...

msgpack5: Deeply nested input can exhaust the decoder stack

Impact The decoder has no nesting-depth limit for arrays and maps. An attacker who can provide MessagePack input can use deeply nested containers to exhaust the JavaScript call stack and interrupt the process or request handler. Patches The decoder now limits nesting depth to 100 by default and...
