Redis — CWE-407 Analysis
=========================

.. contents:: :local:

Overview
--------

Redis is an in-memory key-value store used as a cache, message broker, and streaming
platform. Redis Cluster distributes data across nodes using a consistent hash ring (16384
slots). The replication and sentinel topologies involve small fixed-membership graphs.

Status: **CLEAN** (scanned 2026-03-23)
---------------------------------------

No candidates found in ``src/``.

Triage Notes
------------

Redis's primary data structures (hashtable, skiplist, quicklist, listpack) are all
designed for O(1) or O(log n) access. The cluster topology uses a 16384-slot bitset
for key-space assignment — O(1) slot lookup.

No graph traversal algorithm (SCC, Tarjan, cycle detection, DFS, BFS) is present in
Redis source. Replication topology is a flat star graph (one primary, N replicas) with
membership tracked by integer flags on the ``clusterNode`` struct.
