MITRE ATT&CK
1 technique across 1 tactic: Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Impact | While the CVSS v3.1 score of 4.8 is moderate (AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N), several factors suggest this warrants attention despite the relatively low score. The attack vector is network-accessible (AV:N) requiring no privileges (PR:N) and no user interaction (UI:N), indicating broad exploitability. The moderate attack complexity (AC:H) suggests the attacker must either trigger a specific misconfiguration or understand the allowFrom parameter logic. The lack of KEV or known public POC status cannot be determined from available data, but four distinct commits in the vendor repository indicate a substantive fix addressing multiple aspects of the vulnerability. The real-world risk depends heavily on deployment: organizations using BlueBubbles with default or empty allowFrom configurations face immediate exposure for unauthorized message injection, while properly configured instances are not vulnerable. This is a configuration-dependent rather than unavoidable vulnerability, making it a moderate priority for affected deployments. |
| Exploit ScenarioDerived | An attacker identifies an OpenClaw instance with BlueBubbles plugin enabled and an empty or unconfigured allowFrom parameter through network reconnaissance or credential-free probing. The attacker crafts a message directed to a BlueBubbles account, which bypasses the broken allowlist validation due to the misconfigured allowFrom field. The message is delivered directly to the target's BlueBubbles account without the intended sender authorization checks, allowing the attacker to send unsolicited messages or potentially inject malicious content. The moderate attack complexity (AC:H) suggests the attacker may need prior knowledge of the allowFrom misconfiguration or the ability to trigger its absence through application behavior. |

Alert meAnalysisAIv1 – Mar 18, 2026
OpenClaw versions prior to 2026.2.22 contain an access control bypass vulnerability in the optional BlueBubbles plugin where empty allowFrom configuration causes the allowlist validation logic to fail, enabling remote attackers to send direct messages to BlueBubbles accounts without proper authorization. The vulnerability stems from improper handling of misconfigured sender authorization checks, allowing attackers to circumvent dmPolicy pairing and allowlist restrictions. Patches are available from the vendor, and this is classified as an authentication bypass issue with a CVSS score of 4.8 indicating moderate severity.
RemediationAI
Upgrade OpenClaw to version 2026.2.22 or later, which contains fixes verified across four separate commits (9632b9bcf032c5f2280c3103961fde912ab1f920, 2ba6de7eaad812e5e8603018e14e54e96bfd57dd, 51c0893673de8e5cea64e64351dbfa4680ba0dec, 4540790cb62412676f7b61cfc6e47443f84a251e) available on the vendor's GitHub repository. Prior to upgrading, audit all OpenClaw instances to verify BlueBubbles plugin allowFrom configuration is explicitly set with a whitelist of authorized senders, and ensure dmPolicy pairing is enforced; do not rely on empty or default configurations. If immediate patching is not possible, restrict network access to the OpenClaw instance to trusted networks only and disable the BlueBubbles plugin until the patch can be applied. Refer to the vendor advisory at https://github.com/openclaw/openclaw/security/advisories/GHSA-jwf4-8wf4-jf2m and VulnCheck advisory at https://www.vulncheck.com/advisories/openclaw-bluebubbles-access-control-bypass-via-empty-allowfrom-configuration for additional context.

Technical ContextAI · show details
The vulnerability exists in OpenClaw's BlueBubbles plugin, a messaging integration component (identified via CPE cpe:2.3:a:openclaw:openclaw), and is rooted in CWE-863 (Incorrect Authorization). The root cause is improper validation of the allowFrom configuration parameter; when this field is empty or not properly set, the allowlist validation logic fails to enforce sender authorization checks. The dmPolicy pairing mechanism, which is designed to restrict who can initiate messages, becomes ineffective. This represents a classic authorization bypass where the absence of a required configuration value causes authentication and access control mechanisms to be silently skipped rather than defaulting to a secure state.

Lifecycle Timeline
2DescriptionCVE.org
OpenClaw versions prior to 2026.2.22 with the optional BlueBubbles plugin contain an access control bypass vulnerability where empty allowFrom configuration causes dmPolicy pairing and allowlist restrictions to be ineffective. Remote attackers can send direct messages to BlueBubbles accounts by exploiting the misconfigured allowlist validation logic to bypass intended sender authorization checks.
Executive ViewAI
CVE-2026-22170 presents moderate security risk, a incorrect authorization vulnerability rated CVSS 6.3. Attackers could gain access beyond their authorized level. A patch is available and should be applied during regular vulnerability management.
Apply vendor patch. If patching is delayed: restrict network access and enable monitoring.
