GHSA-XC7W-V5X6-CC87
Vulnerability from github – Published: 2026-02-17 17:14 – Updated: 2026-03-06 01:00Summary
The BlueBubbles webhook handler previously treated any request whose socket remoteAddress was loopback (127.0.0.1, ::1, ::ffff:127.0.0.1) as authenticated. When OpenClaw Gateway is behind a reverse proxy (Tailscale Serve/Funnel, nginx, Cloudflare Tunnel, ngrok), the proxy typically connects to the gateway over loopback, allowing unauthenticated remote requests to bypass the configured webhook password.
This could allow an attacker who can reach the proxy endpoint to inject arbitrary inbound BlueBubbles message/reaction events.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
< 2026.2.12 - Patched versions:
>= 2026.2.12
Exposure / Configuration
- BlueBubbles is an optional channel plugin (intended to eventually replace the legacy iMessage plugin, which is also optional). It is not enabled by default and is not part of a standard OpenClaw configuration.
- Only deployments with the BlueBubbles webhook endpoint exposed through a reverse proxy are impacted.
Details
The BlueBubbles webhook handler accepts inbound events via an HTTP POST endpoint under the configured BlueBubbles webhook path.
In vulnerable versions, the handler would accept requests as authenticated if req.socket.remoteAddress is loopback, without validating forwarding headers. With common reverse-proxy setups, the gateway sees the proxy as the direct client (loopback), even when the original request is remote.
Fix
- Primary fix (released in
2026.2.12): remove loopback-based authentication bypass and require the configured webhook secret. - Defense-in-depth follow-up (next release after commit below): treat requests with forwarding headers as proxied and never accept passwordless webhooks through a proxy.
Fix Commit(s)
f836c385ffc746cb954e8ee409f99d079bfdcd2f(released in2026.2.12)743f4b28495cdeb0d5bf76f6ebf4af01f6a02e5a(defense-in-depth follow-up)
Mitigations
- Ensure a BlueBubbles webhook password is configured.
- Do not expose the gateway webhook endpoint publicly without authentication.
Thanks @simecek for reporting.

GHSA-XFCH-MQ3G-X27H
Vulnerability from github – Published: 2025-09-29 21:30 – Updated: 2025-10-09 18:30Vasion Print (formerly PrinterLogic) Virtual Appliance Host prior to version 22.0.1049 and Application prior to version 20.0.2786 (VA/SaaS deployments) contain a default admin account and an installation‑time endpoint at /admin/query/update_database.php that can be accessed without authentication. An attacker who can reach the installation web interface can POST arbitrary root_user and root_password values, causing the script to replace the default admin credentials with attacker‑controlled ones. The script also contains hard‑coded SHA‑512 and SHA‑1 hashes of the default password, allowing the attacker to bypass password‑policy validation. As a result, an unauthenticated remote attacker can obtain full administrative control of the system during the initial setup. This vulnerability has been identified by the vendor as: V-2024-022 — Insecure Installation Credentials.

Mitigation
- Divide the software into anonymous, normal, privileged, and administrative areas. Identify which of these areas require a proven user identity, and use a centralized authentication capability.
- Identify all potential communication channels, or other means of interaction with the software, to ensure that all channels are appropriately protected, including those channels that are assumed to be accessible only by authorized parties. Developers sometimes perform authentication at the primary channel, but open up a secondary channel that is assumed to be private. For example, a login mechanism may be listening on one network port, but after successful authentication, it may open up a second port where it waits for the connection, but avoids authentication because it assumes that only the authenticated party will connect to the port.
- In general, if the software or protocol allows a single session or user state to persist across multiple connections or channels, authentication and appropriate credential management need to be used throughout.
Mitigation MIT-15
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
Mitigation
- Where possible, avoid implementing custom, "grow-your-own" authentication routines and consider using authentication capabilities as provided by the surrounding framework, operating system, or environment. These capabilities may avoid common weaknesses that are unique to authentication; support automatic auditing and tracking; and make it easier to provide a clear separation between authentication tasks and authorization tasks.
- In environments such as the World Wide Web, the line between authentication and authorization is sometimes blurred. If custom authentication routines are required instead of those provided by the server, then these routines must be applied to every single page, since these pages could be requested directly.
Mitigation MIT-4.5
Strategy: Libraries or Frameworks
- 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 libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator [REF-45].
Mitigation
When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to require strong authentication for users who should be allowed to access the data [REF-1297] [REF-1298] [REF-1302].
CAPEC-12: Choosing Message Identifier
This pattern of attack is defined by the selection of messages distributed via multicast or public information channels that are intended for another client by determining the parameter value assigned to that client. This attack allows the adversary to gain access to potentially privileged information, and to possibly perpetrate other attacks through the distribution means by impersonation. If the channel/message being manipulated is an input rather than output mechanism for the system, (such as a command bus), this style of attack could be used to change the adversary's identifier to more a privileged one.
CAPEC-166: Force the System to Reset Values
An attacker forces the target into a previous state in order to leverage potential weaknesses in the target dependent upon a prior configuration or state-dependent factors. Even in cases where an attacker may not be able to directly control the configuration of the targeted application, they may be able to reset the configuration to a prior state since many applications implement reset functions.
CAPEC-216: Communication Channel Manipulation
An adversary manipulates a setting or parameter on communications channel in order to compromise its security. This can result in information exposure, insertion/removal of information from the communications stream, and/or potentially system compromise.
CAPEC-36: Using Unpublished Interfaces or Functionality
An adversary searches for and invokes interfaces or functionality that the target system designers did not intend to be publicly available. If interfaces fail to authenticate requests, the attacker may be able to invoke functionality they are not authorized for.
CAPEC-62: Cross Site Request Forgery
An attacker crafts malicious web links and distributes them (via web pages, email, etc.), typically in a targeted manner, hoping to induce users to click on the link and execute the malicious action against some third-party application. If successful, the action embedded in the malicious link will be processed and accepted by the targeted application with the users' privilege level. This type of attack leverages the persistence and implicit trust placed in user session cookies by many web applications today. In such an architecture, once the user authenticates to an application and a session cookie is created on the user's system, all following transactions for that session are authenticated using that cookie including potential actions initiated by an attacker and simply "riding" the existing session cookie.
