What is CVE-2026-47722?

The Nebula Mesh control plane used for Slack is susceptible to improper input validation, where operator-supplied fields such as 'ListenHost' and 'TunDevice' are directly interpolated into a configuration template without proper sanitation. This lack of validation can lead to potential security risks. The issue has been addressed in version 0.3.2, which introduced critical fixes to ensure that inputs are verified and safe before processing.

Affected Version(s)

nebula-mesh < 0.3.2
