Description
Summary
In a narrow Signal reaction-notification path, reaction-only inbound events could enqueue a status event before sender access checks were applied.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected:
<= 2026.2.24(latest published at patch time) - Fixed:
2026.2.25
Details
In the affected flow (src/signal/monitor/event-handler.ts), reaction-only handling could return after enqueueSystemEvent(...) before DM/group authorization checks were evaluated for that sender.
This behavior was limited to reaction-only inbound events with reaction notifications enabled. In that case, a sender not authorized for normal DM flow could still queue a Signal reaction status line for that session.
The fix applies shared DM/group access checks before reaction notification enqueue. Pairing behavior for normal DM messages is unchanged.
Impact
- Limited to Signal reaction-only inbound events.
- Could add an unauthorized reaction status line to agent context for affected sessions.
- Did not directly enable normal DM delivery or direct host command execution.

Release Process Note
patched_versions is pre-set to 2026.2.25 so once npm release is out, advisory publish can proceed directly.
OpenClaw thanks @tdjackey 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-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.
