This may lead to denial of service, remote code execution or other unexpected behavior in applications that evaluate user-provided JSONata expressions.\n\n### Patch\n\nThis issue has been fixed in JSONata versions `>= 1.8.7` and `>= 2.0.4`. Applications that evaluate user-provided expressions should update ASAP to prevent exploitation. The following patch can be applied if updating is not possible.\n\n```patch\n--- a/src/jsonata.js\n+++ b/src/jsonata.js\n@@ -1293,6 +1293,13 @@ var jsonata = (function() {\n                 }\n                 for(var ii = 0; ii < matches.length; ii++) {\n                     var match = matches[ii];\n+                    if (match && (match.isPrototypeOf(result) || match instanceof Object.constructor)) {\n+                        throw {\n+                            code: \"D1010\",\n+                            stack: (new Error()).stack,\n+                            position: expr.position\n+                        };\n+                    }\n                     // evaluate the update value for each match\n                     var update = await evaluate(expr.update, match, environment);\n                     // update must be an object\n@@ -1539,7 +1546,7 @@ var jsonata = (function() {\n                 if (typeof err.token == 'undefined' && typeof proc.token !== 'undefined') {\n                     err.token = proc.token;\n                 }\n-                err.position = proc.position;\n+                err.position = proc.position || err.position;\n             }\n             throw err;\n         }\n@@ -1972,6 +1979,7 @@ var jsonata = (function() {\n         \"T1007\": \"Attempted to partially apply a non-function.
