CVE-2026-44993

OpenClaw < 2026.4.20 - Direct Message Misclassification in Feishu Card Actions

Published May 11, 2026 CVSS 4.0 · 2.3 Low EPSS < 1% KEV · Not listed

Description

OpenClaw before 2026.4.20 contains a message classification vulnerability in Feishu card-action callbacks that misclassifies direct messages as group conversations. Attackers can bypass dmPolicy enforcement by triggering card-action flows in direct message conversations that should have been blocked by restrictive policies.

Analysis

Technical impact

OpenClaw before 2026.4.20 includes a message classification flaw in its Feishu card-action callbacks that mistakenly treats direct messages as group conversations. As a result, attackers can provoke card-action flows within private chats that should normally be blocked by dmPolicy restrictions. This flaw allows policy enforcement to be bypassed for direct message contexts, potentially enabling unauthorized card actions. The vulnerability exploits incorrect classification logic, identified as CWE-184.

Affected Systems

The affected product is OpenClaw, all releases older than version 2026.4.20. The vulnerability affects the Node.js runtime component used by the application. Users running any version before the 2026.4.20 release are at risk.

Risk and Exploitability

The CVSS score of 2.3 indicates a low severity overall. EPSS data is not available, so the likelihood of exploitation is uncertain, but the issue is not in the CISA KEV catalog. The probable attack vector is an attacker sending a crafted Feishu card-action request in a direct message, requiring the ability to initiate a card-action flow in a private conversation. No additional preconditions are listed beyond interacting with the Feishu integration. The risk remains limited but any bypass of dmPolicy enforcement can undermine policy controls.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Upgrade OpenClaw to version 2026.4.20 or later to remove the misclassification bug.
If your organization requires strict separation of card actions in direct messages, disable the Feishu card-action callback for direct conversations in the OpenClaw configuration.
Continuously monitor OpenClaw logs for unexpected card-action activity and adjust dmPolicy settings as needed to ensure policy enforcement remains effective.
