CVE-2026-14362 (opens in a new tab)How to fix?
Upgrade github.com/hashicorp/memberlist to version 0.6.0 or higher.
Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the push/pull state-handling process. An attacker can cause memory exhaustion and terminate the process by sending crafted network traffic to the gossip listener. This is only exploitable if the component is configured to run as a live gossip agent with the gossip listener enabled and accessible over the network.
Workaround
This vulnerability can be mitigated by restricting network access to the gossip port (UDP/TCP, commonly 7946 or 9094) to trusted cluster members only, for example via network policy, firewall rules, or security groups.
