      <body xmlns="http://www.w3.org/1999/xhtml">
	<p>cJSON through 1.7.19 applies RFC 6902 JSON Patch operations
	non-atomically in apply_patch() in cJSON_Utils.c. For a replace
	operation that is missing its value member, or a move operation whose
	destination path cannot be resolved, the existing target member is
	detached and deleted before the operation is fully validated, so the
	target document is mutated while cJSONUtils_ApplyPatches() or
	cJSONUtils_ApplyPatchesCaseSensitive() returns a failure status. An
	attacker who can supply the patch document can destroy addressable
	members of the target document even though the API reports that the
	patch failed, defeating the all-or-nothing behavior callers rely on to
	reject bad patches.</p>
