CVE-2024-21534Public exploitNetwork attack vector

Code execution via unsafe JSONPath expression evaluation

Published Oct 11, 2024 · Updated Nov 18, 2024

Code injection in jsonpath-plus before 10.2.0 allows remote attackers to execute arbitrary code through crafted JSONPath expressions. The Node.js evaluator permits inherited constructor-property access from untrusted path expressions, allowing Function to run code outside the intended safe evaluator. Exploitation requires a consuming application to pass attacker-controlled JSONPath expressions, and resulting code runs with that application's process privileges.
