{"id":"BIT-keydb-2022-36021","summary":"Redis string pattern matching can be abused to achieve Denial of Service","details":"Redis is an in-memory database that persists on disk. Authenticated users can use string matching commands (like `SCAN` or `KEYS`) with a specially crafted pattern to trigger a denial-of-service attack on Redis, causing it to hang and consume 100% CPU time.
