OpenClaw's Zalouser allows wrong groups to send messages
GHSA-f5mf-3r52-r83w
Summary
OpenClaw's Zalouser software had a bug that allowed the wrong group to send messages to an agent if group names were used instead of stable IDs. This made it possible for unintended messages to reach the agent. To fix this, update to OpenClaw version 2026.3.12 or later.
What to do
- Update openclaw to version 2026.3.12.
Affected software
| Vendor | Product | Affected versions | Fix available |
|---|---|---|---|
| – | openclaw | <= 2026.3.11 | 2026.3.12 |
Original title
OpenClaw's Zalouser allowlist authorization matched mutable group names by default
Original description
### Summary
OpenClaw's Zalouser allowlist mode accepted mutable group names and normalized slugs as authorization matches instead of requiring stable group IDs. In deployments that used name-based `channels.zalouser.groups` entries together with permissive sender allowlists, a different group could be accepted by reusing the same display name as an allowlisted group.
### Impact
This weakened channel authorization for Zalouser group routing and could allow messages from an unintended group to reach the agent when operators relied on group names instead of stable IDs.
### Affected versions
`openclaw` `<= 2026.3.11`
### Patch
Fixed in `openclaw` `2026.3.12`. Allowlist authorization now matches stable group identifiers, and users should update to `2026.3.12` or later.
