OpenClaw's Signal reaction-only status events could, in limited cases, be enqueued before access checks
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.

Frequently Asked Questions
A security vulnerability is a weakness in software, hardware, or configuration that can be exploited to compromise confidentiality, integrity, or availability. Many vulnerabilities are tracked as CVEs (Common Vulnerabilities and Exposures), which provide a standardized identifier so teams can coordinate patching, mitigation, and risk assessment across tools and vendors.
CVSS (Common Vulnerability Scoring System) estimates technical severity, but it doesn't automatically equal business risk. Prioritize using context like internet exposure, affected asset criticality, known exploitation (proof-of-concept or in-the-wild), and whether compensating controls exist. A "Medium" CVSS on an exposed, production system can be more urgent than a "Critical" on an isolated, non-production host.
A vulnerability is the underlying weakness. An exploit is the method or code used to take advantage of it. A zero-day is a vulnerability that is unknown to the vendor or has no publicly available fix when attackers begin using it. In practice, risk increases sharply when exploitation becomes reliable or widespread.
Recurring findings usually come from incomplete Asset Discovery, inconsistent patch management, inherited images, and configuration drift. In modern environments, you also need to watch the software supply chain: dependencies, containers, build pipelines, and third-party services can reintroduce the same weakness even after you patch a single host. Unknown or unmanaged assets (often called Shadow IT) are a common reason the same issues resurface.
Use a simple, repeatable triage model: focus first on externally exposed assets, high-value systems (identity, VPN, email, production), vulnerabilities with known exploits, and issues that enable remote code execution or privilege escalation. Then enforce patch SLAs and track progress using consistent metrics so remediation is steady, not reactive.
SynScan combines attack surface monitoring and continuous security auditing to keep your inventory current, flag high-impact vulnerabilities early, and help you turn raw findings into a practical remediation plan.
