Description

rpk in Redpanda before 23.1.2 mishandles the redpanda.rpc_server_tls field, leading to (for example) situations in which there is a data type mismatch that cannot be automatically fixed by rpk, and instead a user must reconfigure (while a cluster is turned off) in order to have TLS on broker RPC ports. NOTE: the fix was also backported to the 22.2 and 22.3 branches.

Affected products

• Redpanda: before 23.1.2 — fixed in 23.1.2

How to fix

Upgrade to a fixed version: Redpanda 23.1.2. Check the vendor advisory for mitigations.
