| Titre | Davide Faconti BehaviorTree 4.7.0 / master commit 8d47d39 NULL Pointer Dereference |
|---|
| Description | BehaviorTree.CPP version 4.7.0 (master commit 8d47d39) is vulnerable to a null pointer dereference / invalid JSON access in the JsonExporter::fromJson() function (src/json_export.cpp).
The function assumes the presence of a __type field and directly indexes into JSON objects without validating their structure. When the source parameter is a JSON array whose first element is not an object (or when the __type field is missing), the code attempts to access source[0]["__type"], resulting in undefined behavior.
This leads to a segmentation fault in nlohmann::json::is_object() when dereferencing a null internal pointer.
