Vulnerability from github – Published: 2026-03-12 16:36 – Updated: 2026-03-13 13:35

Summary
ZeptoClaw: Generic webhook channel trusts caller-supplied identity fields; allowlist is checked against untrusted payload data
Details

Summary

The generic webhook channel trusts caller-supplied identity fields (sender, chat_id) from the request body and applies authorization checks to those untrusted values. Because authentication is optional and defaults to disabled (auth_token: None), an attacker who can reach POST /webhook can spoof an allowlisted sender and choose arbitrary chat_id values, enabling high-risk message spoofing and potential IDOR-style session/chat routing abuse.

Details

Relevant code paths:

  • src/channels/webhook.rs:121 sets runtime default auth_token: None.
  • src/config/types.rs:910 also defaults webhook config auth_token to None.
  • src/channels/webhook.rs:224 (validate_auth) explicitly allows requests when no token is configured.
  • src/channels/webhook.rs:128 defines WebhookPayload with identity fields fully controlled by caller input:
  • sender: String
  • chat_id: String
  • src/channels/webhook.rs:421 performs allowlist authorization using payload.sender.
  • src/channels/webhook.rs:433 and src/channels/webhook.rs:434 create InboundMessage using untrusted payload.sender and payload.chat_id.

Why this is vulnerable:

  • The system treats user-provided JSON identity as authoritative identity.
  • Allowlist enforcement does not verify sender authenticity beyond that payload value.
  • chat_id is also attacker-controlled, so routing/session association can be steered to arbitrary chats/conversations.
  • If the webhook is exposed without strong upstream authn/authz controls, spoofing is straightforward.

PoC

  1. Configure the webhook channel in a vulnerable posture (common default behavior):
  2. enabled = true
  3. bind_address = "0.0.0.0" (or any reachable interface)
  4. port = 9876
  5. path = "/webhook"
  6. auth_token = null (or omitted)
  7. allow_from = ["trusted-user-1"]
  8. deny_by_default = true
  9. Start ZeptoClaw.
  10. Send a forged request with attacker-chosen sender and chat_id, without any Authorization header:
curl -i -X POST "http://127.0.0.1:9876/webhook" \
  -H "Content-Type: application/json" \
  --data '{
    "message":"FORGED: run privileged workflow",
    "sender":"trusted-user-1",
    "chat_id":"victim-chat-42"
  }'
  1. Observe:
  2. Response is HTTP/1.1 200 OK.
  3. Message is accepted as if it originated from trusted-user-1.
  4. Message is routed under attacker-chosen chat_id (victim-chat-42).

Impact

  • Vulnerability type:
  • Authentication/authorization bypass (identity spoofing)
  • IDOR-style routing/control issue via attacker-chosen chat_id
  • Affected deployments:
  • Any deployment exposing the generic webhook endpoint without strict upstream authentication and identity binding.
  • Security consequences:
  • Forged inbound messages from spoofed trusted users.
  • Bypass of allowlist intent by injecting allowlisted sender IDs in payload.
  • Cross-chat/session contamination or hijacking by choosing arbitrary chat_id.
  • Potential unauthorized downstream agent/tool actions triggered by malicious input.

Mitigation
Architecture and Design
  • 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
Architecture and Design

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
Architecture and Design
  • 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
Architecture and Design

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
Implementation System Configuration Operation

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.
