CVE-2026-34503 — OpenClaw < 2026.3.28 - Incomplete WebSocket Session Termination on Device Removal and Token Revocation

Affected: OpenClaw

OpenClaw before 2026.3.28 fails to disconnect active WebSocket sessions when devices are removed or tokens are revoked. Attackers with revoked credentials can maintain unauthorized access through existing live sessions until forced reconnection.

GHSA-2pr2-hcv6-7gwv — OpenClaw's device removal and token revocation do not terminate active WebSocket sessions

Affected: npm: openclaw

## Summary

Removing a device or revoking its token updated stored credentials but did not disconnect already-authenticated WebSocket sessions.

## Impact

A revoked device could continue using its existing live session until reconnect, extending access beyond credential removal.

## Affected Component

`src/gateway/server-methods/devices.ts, src/gateway/server.impl.ts`

## Fixed Versions

- Affected: `<= 2026.3.24` - Patched: `>= 2026.3.28` - Latest stable `2026.3.28` contains the fix.

## Fix

Fixed by commit `7a801cc451` (`Gateway: disconnect revoked device sessions`).

OpenClaw thanks @AntAISecurityLab for reporting.
