Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the tokensFromInput() method of TreePointer, which parses JSON Pointer segments with repeated substring() calls that copy the remaining string each iteration (O(n^2)) and accumulates the parsed tokens into an unbounded ArrayList. An attacker can consume CPU quadratically and exhaust the JVM heap by supplying a JSON Pointer with a very large number of segments, on the order of 200,000 or more. This requires the application to parse an attacker-controlled JSON Pointer, which reaches this library through JSON Patch operations, JSON Schema references, or API parameters via json-schema-validator and json-patch.
