CVE-2026-41358
|
| Summary | OpenClaw: Slack thread context could include messages from non-allowlisted senders ## Summary Before OpenClaw 2026.4.2, Slack thread starter and thread-history context fetched through the API was not filtered by the effective sender allowlist. Messages from non-allowlisted senders could still enter the agent context when an allowlisted user replied in the same thread. ## Impact A Slack deployment that relied on sender allowlists could still feed non-allowlisted thread content into the model context through thread history. This was a sender-access-control bypass on Slack thread context, not a direct channel-auth bypass. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `<= 2026.4.1` - Patched versions: `>= 2026.4.2` - Latest published npm version: `2026.4.1` ## Fix Commit(s) - `ac5bc4fb37becc64a2ec314864cca1565e921f2d` — filter Slack thread context by the effective allowlist ## Release Process Note The fix is present on `main` and is staged for OpenClaw `2026.4.2`. Publish this advisory after the `2026.4.2` npm release is live. OpenClaw thanks @AntAISecurityLab for reporting. |
