Sandbox Bypass in OpenClaw Subagents Enables Privilege Escalation

Publication date: 2026-03-29

Last updated on: 2026-03-31

Assigner: VulnCheck

Description
OpenClaw before 2026.3.11 contains a sandbox boundary bypass vulnerability allowing leaf subagents to access the subagents control surface and resolve against parent requester scope instead of their own session tree. A low-privilege sandboxed leaf worker can steer or kill sibling runs and cause execution with broader tool policies by exploiting insufficient authorization checks on subagent control requests.

Mitigation Strategies

The recommended immediate step to mitigate this vulnerability is to upgrade OpenClaw to version 2026.3.11 or later.

This update removes subagents control access from leaf subagents by default, restricts subagent control to the caller’s own descendant sessions, and rejects any steer or kill requests targeting runs outside that descendant tree, thereby fixing the sandbox boundary bypass issue.

Executive Summary

CVE-2026-32915 is a sandbox boundary bypass vulnerability in OpenClaw versions before 2026.3.11. It occurs because leaf subagents, which are supposed to be confined to their own session trees, can improperly access the subagents control surface and resolve control requests against the parent requester scope instead. This means a low-privilege sandboxed leaf worker can manipulate sibling subagent runs by steering or killing them, actions that should be restricted. The root cause is insufficient authorization checks on subagent control requests, allowing unauthorized control beyond intended boundaries.

The vulnerability is classified under CWE-269 (Improper Privilege Management) and CWE-863 (Incorrect Authorization). It allows execution with broader tool policies than intended, effectively bypassing sandbox and session-scope boundaries.

Impact Analysis

This vulnerability can have serious impacts by allowing a low-privilege sandboxed leaf worker to escalate privileges within the OpenClaw environment. Specifically, it can manipulate sibling subagent runs by steering or terminating them, potentially disrupting operations or causing unauthorized execution of actions under broader tool policies.

The impact includes high confidentiality, integrity, and availability risks, as unauthorized control can lead to data exposure, unauthorized modifications, and denial of service within the affected system.

Compliance Impact

The provided information does not specify how CVE-2026-32915 affects compliance with common standards and regulations such as GDPR or HIPAA.
