- Summary
- expr-eval does not restrict functions passed to the evaluate function
- Details
-
The expr-eval library is a JavaScript expression parser and evaluator designed to safely evaluate mathematical expressions with user-defined variables. However, due to insufficient input validation, an attacker can pass a crafted variables object into the evaluate() function and trigger arbitrary code execution.
