CVE-2026-53860: Sender Policy Bypass in OpenClaw BlueBubbles Integration

Vulnerability ID: CVE-2026-53860
CVSS Score: 4.2
Published: 2026-06-18

CVE-2026-53860 details an authorization bypass in the OpenClaw AI gateway's BlueBubbles integration. The vulnerability arises because the sender policy check validates mutable conversation-level metadata rather than verified, stable sender identities. This allows unauthorized group chat participants to manipulate metadata, match allowlist rules, and run unauthorized AI agent actions.

TL;DR

A vulnerability in OpenClaw's BlueBubbles integration allows unauthorized participants to bypass sender validation by manipulating conversation metadata. Upgrading to version 2026.5.7 resolves the flaw by enforcing checks on stable sender identities.

Technical Details

CWE ID: CWE-807 / CWE-863
Attack Vector: Network
CVSS v3.1: 4.2 (Medium)
EPSS Score: 0.00136 (Percentile: 3.38%)
Impact: Sender Policy Bypass & Unauthorized Command Execution
Exploit Status: No public PoC or active exploitation
CISA KEV Status: Not Listed

Affected Systems

OpenClaw < 2026.5.7
openclaw: < 2026.5.7 (Fixed in: 2026.5.7)

Mitigation Strategies

Upgrade to OpenClaw version 2026.5.7 or later
Strictly use stable, immutable sender identifiers (phone numbers, iCloud emails) in policies
Restrict permissions to alter group chat metadata within BlueBubbles
Limit the permissions and tools accessible by the AI agent

Remediation Steps:

Verify current OpenClaw version using the package manager
Update the openclaw package to version 2026.5.7 via npm or your deployment pipeline
Inspect existing configuration files to replace conversation-level allowlist rules with verified sender handles
Restart the OpenClaw gateway service to apply the updated configuration
