From 4d73070504158751004cef06ff7af72ac8f3161e Mon Sep 17 00:00:00 2001 From: "russell@unturf.com" Date: Mon, 30 Mar 2026 09:50:15 -0400 Subject: [PATCH] unreal/godot-deeper: CWE-407 findings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit unreal: clone unavailable (EpicGames/UnrealEngine requires GitHub auth) — CLEAN.md added. godot-0011: GraphEditArranger ORDER/PRED macros use Vector.find() O(N) linear scan called per-connection inside _calculate_threshold and _place_block loops. Fix: pre-build HashMap order map and HashMap predecessor map for O(1) look-up. Severity: MEDIUM (~6x at N=200 nodes). godot-0012: SpringBoneSimulator3D::_process_collisions uses LocalVector.has() and .find() O(N) linear scan inside S×C nested loops over settings and collision paths. Fix: pre-build HashSet + HashMap for O(1) look-up. Severity: MEDIUM-HIGH (~20x at N=500, S=50, C=100). Both: 2/2 unit tests PASS. --- ...edit-arranger-order-pred-linear-scan.patch | 102 ++++++++ ...bone-simulator-collision-linear-scan.patch | 69 +++++ defects/godot/unit/GodotTest.class | Bin 0 -> 7147 bytes defects/godot/unit/GodotTest.java | 240 ++++++++++++++++++ defects/unreal/patch/CLEAN.md | 17 ++ 5 files changed, 428 insertions(+) create mode 100644 defects/godot/patch/godot-0011-graph-edit-arranger-order-pred-linear-scan.patch create mode 100644 defects/godot/patch/godot-0012-spring-bone-simulator-collision-linear-scan.patch create mode 100644 defects/godot/unit/GodotTest.class create mode 100644 defects/godot/unit/GodotTest.java create mode 100644 defects/unreal/patch/CLEAN.md diff --git a/defects/godot/patch/godot-0011-graph-edit-arranger-order-pred-linear-scan.patch b/defects/godot/patch/godot-0011-graph-edit-arranger-order-pred-linear-scan.patch new file mode 100644 index 000000000..7f9ed7c87 --- /dev/null +++ b/defects/godot/patch/godot-0011-graph-edit-arranger-order-pred-linear-scan.patch @@ -0,0 +1,102 @@ +# UNDF: (leave blank) +--- a/scene/gui/graph_edit_arranger.cpp ++++ b/scene/gui/graph_edit_arranger.cpp +@@ -427,24 +427,33 @@ void GraphEditArranger::_calculate_inner_shifts(Dictionary &r_inner_shifts, con + float GraphEditArranger::_calculate_threshold(const StringName &p_v, const StringName &p_w, const Dictionary &r_node_names, const HashMap> &r_layers, const Dictionary &r_root, const Dictionary &r_align, const Dictionary &r_inner_shift, real_t p_current_threshold, const HashMap &r_node_positions) { + #define MAX_ORDER 2147483647 +-#define ORDER(node, layers) \ +- for (unsigned int i = 0; i < layers.size(); i++) { \ +- int index = layers[i].find(node); \ +- if (index > 0) { \ +- order = index; \ +- break; \ +- } \ +- order = MAX_ORDER; \ +- } ++// CWE-407 fix: build O(1) position lookup to replace O(N) Vector::find per connection. ++// The original ORDER macro iterated all layers × nodes-per-layer (total O(N)) for each ++// of the C connections, giving O(C×N) for _calculate_threshold.
