Redis 8.0.1 and later: the Vector Sets module's JSON parser (modules/vector-sets/fastjson.c) recurses without a depth limit when evaluating filter expressions over vector attributes, so an authenticated client can store deeply nested JSON arrays and crash the server with a stack overflow (DoS). Fixed in 8.2.10, 8.4.7, 8.6.7, 8.8.3 and 8.10.2; 8.0.x and unstable/8.12 remain unfixed.
