OpenClaw: Image Tool `tools.fs.workspaceOnly` Bypass via Sandbox Bridge Mounts

Medium npm

Severity: 0.0 / 10; Medium · CVSS 4.0
Exploit chance (EPSS): 0.29%; Chance of exploitation in the next 30 days. Higher than 21.21% of scored vulnerabilities.
Known exploited: No; Not in CISA's catalog
Weakness: CWE-668 Exposure of Resource to Wrong Sphere; CWE-863 Incorrect Authorization
Fix: 2026.3.2; Upgrade openclaw to this version or later

Description

Summary

The image tool did not fully honor the tools.fs.workspaceOnly filesystem boundary. In affected releases, image-path resolution could still traverse sandbox bridge mounts outside the workspace and read files from mounted directories that the other file tools would reject.

Affected Packages / Versions

Affected: < 2026.3.2
Fixed: >= 2026.3.2

Release Status

The complete fix shipped in v2026.3.2 and remains present in v2026.3.23 and v2026.3.23-2.

Code-Level Confirmation

src/agents/openclaw-tools.ts now passes fsPolicy into createImageTool, so the image tool receives the same workspace-only policy input as the other filesystem tools.
src/agents/tools/image-tool.ts, src/agents/tools/media-tool-shared.ts, and src/agents/sandbox-media-paths.ts now restrict local roots and sandbox-bridge resolution to the workspace when tools.fs.workspaceOnly is enabled.

OpenClaw thanks @YLChen-007 for reporting.

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness

CWE-668: Exposure of Resource to Wrong Sphere

The product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource.

CWE-863: Incorrect Authorization

The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.

How to prevent it

Architecture and Design: Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries. Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Architecture and Design: Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].
Architecture and Design: Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Architecture and Design: For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page. One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
System Configuration, Installation: Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
