GHSA-g353-mgv3-8pcj — high GitHub Advisory (CVE-2026-32974) in npm/openclaw

Description

Summary

Feishu webhook mode allowed deployments that configured only verificationToken without encryptKey. In that state, forged inbound events could be accepted because the weaker configuration did not provide the required cryptographic verification boundary.

Impact

An unauthenticated network attacker who could reach the webhook endpoint could inject forged Feishu events, impersonate senders, and potentially trigger downstream tool execution subject to the local agent policy.

Affected versions

openclaw <= 2026.3.11

Patch

Fixed in openclaw 2026.3.12. Feishu webhook mode now fails closed unless encryptKey is configured, and the webhook transport rejects missing or invalid signatures before dispatch. Update to 2026.3.12 or later and configure encryptKey for webhook deployments.

Attack complexity (AC:L) Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup. Privileges required (PR:N) No account or special rights needed—anonymous or random user is enough. User interaction (UI:N) Nobody has to click “OK” or open a trap file; it can work without a victim helping. Scope (S:U) Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems. Confidentiality (C:L) Some sensitive info could get out, but not a total data dump. Integrity (I:H) They could widely tamper with or forge data—trust in the data is badly hurt. Availability (A:L) Might cause slowdowns, glitches, or partial disruption—not a full brick.
