Redis: Security Fixes and Replication Reliability
Three security fixes merged for cluster memory safety and Lua scripting isolation, while new proposals would verify TLS by default and harden redis-cli. Replication and IO thread work adds finer control over threading and fixes cluster reset durability.

Good morning, it's Thursday, October 22nd, 2026.
Lead insight: Security is the clear signal today, with three merged fixes closing remote crash and protocol desync paths, alongside proposals to make clients distrust malicious servers by default.
First, merged cluster and scripting fixes. Pull request 15685 fixes a remote use-after-free in cluster bus handling of forgotten node messages, where a packet naming its own sender could free the connection buffer while still being parsed, with demonstrated remote code execution impact. The fix ignores entries that…
Second, proposed client hardening still under review. Pull request 16033 would verify TLS server identity by default in redis-cli, redis-benchmark and Sentinel, and reject IP addresses in the expected peer name option. Pull request 16034 hardens redis-cli's command docs parser against a compromised server that sends…
Finally, replication control and correctness. Merged pull request 15913 adds an I-O threads client types setting to choose which connections use I-O workers — normal clients, replicas, primaries, or only compressed replication — so CPU-heavy replication compression can be offloaded while others stay on the main…
