CVE-2026-41362 is a low-severity Exposure of Resource to Wrong Sphere (CWE-668) vulnerability in Openclaw Openclaw. Its CVSS base score is 2.3 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 20th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-4 (Information Flow Enforcement) and SC-4 (Information in Shared System Resources) — see the control section below for these in your framework.

Vulnerability Data
OpenClaw versions 2026.2.19 before 2026.3.31 contain an improper cache isolation vulnerability in the Zalo webhook replay-dedupe mechanism that is shared across authenticated webhook targets. Attackers controlling one authenticated Zalo webhook path in multi-account deployments can suppress legitimate events on different…

accounts by matching event_name and message_id parameters.

Why these techniques?
Vulnerability enables cross-tenant suppression of webhook events via shared cache, directly facilitating application-layer DoS through exploitation of the replay-dedupe logic.

Control response
Mitigating Controls (NIST 800-53 r5) AI
Directly prevents unauthorized information transfer (event suppression) through the shared replay-dedupe cache across authenticated webhook accounts.
Enforces information flow policies so that deduplication metadata from one account's webhook cannot affect events belonging to other accounts.
Access enforcement must be applied to the cache keys (event_name + message_id) to ensure operations are confined to the authenticated account's scope.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Enforcing least-privilege authorizations directly prevents resources from being exposed outside their intended control sphere.
Network segmentation and unauthorized-access protections reduce the chance of resources being reachable by the wrong sphere.

Placing systems of differing trust levels into separate domains prevents resources from being placed in a sphere where they are reachable by unintended actors.
Requiring owners to manage the full asset life cycle and remove assets from the inventory upon secure disposal helps prevent resources from being inadvertently exposed outside their intended security sphere.
