CVE-2026-77414

JSONata is a JSON query and transformation language. Prior to 1.8.8 and 2.2.1, the src/jsonata.js environment.lookup function used a bypassable hasOwnProperty check. Crafted expressions could use $hasOwnProperty, $spread, $string, prototype access, and $constructor to reach the object prototype a...

CVE-2026-77413

JSONata is a JSON query and transformation language. Prior to 1.8.8 and 2.2.0, the src/functions.js lookup function lacked an Object.prototype.hasOwnProperty check and allowed crafted expressions to access inherited prototype members. An attacker able to supply an expression could use inherited...

CVE-2026-77415

JSONata is a JSON query and transformation language. Prior to 1.8.8 and 2.2.1, crafted JSONata expressions could chain several object-integrity weaknesses to execute arbitrary code. The chain could overwrite $clone to mutate objects through evaluateTransformExpression, expose and deconstruct...

Arbitrary Code Injection

Overview jsonata is a JSON query and transformation language Affected versions of this package are vulnerable to Arbitrary Code Injection via crafted expressions that exploit the evaluateTransformExpression and applyProcedure functions. An attacker can execute arbitrary code by submitting special...

JSONata vulnerable to Arbitrary Code Execution via crafted JSONata expressions

Before JSONata 2.2.1 and 1.8.8 it was possible to execute arbitrary code with crafted expressions, due to: - overwriting $clone allowing mutation of objects via transforms see evaluateTransformExpression - it being possible to destruct jsonata functions/lambdas e.g. $merge. - applyProcedure using...
