Redis shipped seven security releases on July 23 after researchers published authenticated RCE PoCs for stock Redis 6.2.22, 7.4.9, 8.6.4, and 8.8.0.

All four chains require RESTORE. The Streams chains also need EVAL and XGROUP; the 8.8.0 chain needs EVAL and the bundled RedisBloom module. Redis says the underlying memory flaws may lead to remote code execution.

Redis 6.2.23, 7.2.15, and 7.4.10 fix the Streams shared-NACK use-after-free; Redis 8.2.8, 8.4.5, and 8.6.5 fix both the Streams issue and the RedisBloom and TDigest out-of-bounds writes; Redis 8.8.1 fixes the RedisBloom and TDigest loaders, while the Streams guard was already present in Redis 8.8.0.
