Redis

Redis is an in-memory data store and caching layer deeply embedded across web applications, microservices, and real-time systems, where its compact codebase and network exposure create a high-value target despite a narrow product portfolio. Vulnerabilities affecting the vendor skew toward serious outcomes, with an elevated share reaching critical severity, reflecting the memory-safety and parsing demands of a C-based system handling untrusted network input. The recurring exposure centers on integer overflow, buffer overflow, and improper input validation across the core Redis server and language-specific client libraries such as redis-py and hiredis, weakness classes typical of low-level data-structure and protocol-parsing code. Defenders should prioritize Redis instances exposed to untrusted networks and maintain close attention to security updates, as the vendor's ubiquity in caching tiers makes its flaws broadly consequential; current exploitation activity and severity counts are shown alongside this summary.
