GHSA-x2ff-j5c2-ggpr OpenClaw: Slack interactive callbacks could skip configured sender checks in some shared-workspace flows

• npm openclaw: < 2026.2.25 → fixed in 2026.2.25

Impact In shared Slack workspace deployments that rely on sender restrictions (`allowFrom`, DM policy, or channel user allowlists), some interactive callbacks (`block_action`, `view_submission`, `view_closed`) could be accepted before full sender authorization checks. In that scenario, an unauthorized workspace member could enqueue system-event text into an active session. This issue did not provide unauthenticated access, cross-gateway isolation bypass, or host-level privilege escalation by itself. Affected Packages / Versions • Package: `openclaw` (npm) • Vulnerable versions: `<= 2026.2.24` • Patched version: `2026.2.25` (planned next npm release) Fix Commit(s) • `ce8c67c314b93f570f53c2a9abc124e1e3a54715` Release Process Note `patched_versions` is pre-set to the release (`2026.2.25`). Advisory published with npm release `2026.2.25`. Trust Model Scope Note OpenClaw does not support adversarial multi-user isolation on a single shared gateway instance. The supported model is one trust boundary per gateway (separate gateways/hosts for mutually untrusted users). See: https://docs.openclaw.ai/gateway/security OpenClaw thanks @tdjackey for reporting.
