| Title | java-json-tools json-patch 1.13 Broken Access Control |
|---|
| Description | Unrestricted Copy/Move Operations Enable Intra-Document Data Exfiltration
The copy and move operations in JSON Patch accept any from path without access control validation. An attacker can use copy to read values from internal/sensitive fields and write them to user-visible locations, effectively exfiltrating data that should not be accessible. The library provides no mechanism to restrict which paths can be used as from sources.
