russell@unturf.com 7491349edc game-engines: allegro5/bullet3/box2d/dry CWE-407 scan 
bullet3-0001: btGhostObject::addOverlappingObjectInternal O(N²) linear dedup
  per broadphase step — even carries "too slow" self-admission comment (HIGH)
bullet3-0002: btSoftRigidCollisionAlgorithm::processCollision O(C×D) per
  frame on m_collisionDisabledObjects plain array (MEDIUM)
allegro5: CLEAN (vector_contains only on non-hot setup paths)
box2d: CLEAN (v3 rewrite uses b2HashSet throughout)
dry: CLEAN (HashSet/HashMap on all hot dedup paths)

zulip — CWE-407 Scan: CLEAN

Scanned: 2026-03-29

Scope

  • zerver/lib/thumbnail.py — seen_thumbnails: set() based (line 939 context: set())
  • zerver/lib/onboarding.py — seen_topics = set() (line 561)
  • Message thread traversal, user group membership, notification dispatch: checked

Verdict

No CWE-407 (algorithmic complexity / quadratic membership check) defects found. All deduplication uses set. No list-based visited/seen patterns in message threading, group membership, or notification hot paths.
