Object prototype pollution via transform operator updates
Published Mar 6, 2024 · Updated Aug 13, 2024
Prototype pollution in JSONata 1.4.0 through 1.8.6 and 2.0.0 through 2.0.3 allows attackers to alter objects via transform expressions. The transform evaluator applies an update to selector matches without rejecting the Object constructor or its prototype, allowing properties such as is_admin to be written there. Exploitation requires a consuming application to evaluate attacker-supplied JSONata expressions and can corrupt process behavior, interrupt service, or enable code execution depending on that application's use of polluted properties.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
