Title
Indico missing access check in event series management API
Summary
Indico is an event management system that uses Flask-Multipass, a multi-backend authentication system for Flask. In versions prior to 3.3.11, the API endpoint used to manage event series is missing an access check, allowing unauthenticated/unauthorized access to this endpoint. The impact of this is limited to getting the metadata (title, category chain, start/end date) for events in an existing series, deleting an existing event series, and modifying an existing event series. This vulnerability does NOT allow unauthorized access to events (beyond the basic metadata mentioned above), nor any kind of tampering with user-visible data in events. Version 3.3.11 fixes the issue. As a workaround, use the webserver to restrict access to the series management API endpoint.

OpenClaw 2026.1.20 < 2026.2.1 - Missing Authentication in Browser Relay /cdp WebSocket Endpoint
Summary
OpenClaw version 2026.1.20 prior to 2026.2.1 contains a vulnerability in the Browser Relay (extension must be installed and enabled) /cdp WebSocket endpoint in which it does not require authentication tokens, allowing websites to connect via loopback and access sensitive data. Attackers can exploit this by connecting to ws://127.0.0.1:18792/cdp to steal session cookies and execute JavaScript in other browser tabs.

CVE-2026-28472 (GCVE-0-2026-28472)
Vulnerability from cvelistv5 – Published: 2026-03-05 21:59 – Updated: 2026-03-09 18:04

Title
OpenClaw < 2026.2.2 - Device Identity Check Bypass in Gateway WebSocket Connect Handshake
Summary
OpenClaw versions prior to 2026.2.2 contain a vulnerability in the gateway WebSocket connect handshake in which it allows skipping device identity checks when auth.token is present but not validated. Attackers can connect to the gateway without providing device identity or pairing by exploiting the presence check instead of validation, potentially gaining operator access in vulnerable deployments.
Severity
8.1 (High)

Title
OpenClaw 2026.1.5 < 2026.2.12 - Missing Authentication in Browser Control HTTP Endpoints
Summary
OpenClaw versions 2026.1.5 prior to 2026.2.12 fail to enforce mandatory authentication on the /agent/act browser-control HTTP route, allowing unauthorized local callers to invoke privileged operations. Remote attackers on the local network or local processes can execute arbitrary browser-context actions and access sensitive in-session data by sending requests to unauthenticated endpoints.

Title
OpenClaw < 2026.2.14 - Webhook Signature Verification Bypass via ngrok Loopback Compatibility
Summary
OpenClaw versions prior to 2026.2.14 contain a webhook signature-verification bypass in the voice-call extension that allows unauthenticated requests when the tunnel.allowNgrokFreeTierLoopbackBypass option is explicitly enabled. An external attacker can send forged requests to the publicly reachable webhook endpoint without a valid X-Twilio-Signature header, resulting in unauthorized webhook event handling and potential request flooding attacks.

Mitigation
Phase: Architecture and Design
Description:
- 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 ID: MIT-15
Phase: Architecture and Design
Description:
- 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.

Phase: Architecture and Design
Description:
- 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 ID: MIT-4.5
Phase: Architecture and Design
Strategy: Libraries or Frameworks
Description:
- 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
Phases: Implementation, System Configuration, Operation
Description:
- 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.
