What it is

OpenClaw (npm package `openclaw`) before 2026.7.1 does not enforce the documented owner-only requirement for persistent `/activation` policy changes in group channels. An authorized non-owner channel sender can change whether the agent requires mention-based activation, causing the agent to respond more broadly in the group (exposing its responses to additional group traffic) or suppressing expected activation behavior until an owner restores the intended setting. The issue is fixed in version 2026.7.1.
