OpenClaw npm Package Credential Exposure to Wrong Endpoint

Publication date: 2026-09-26

Last updated on: 2026-09-26

Assigner: VulnCheck

Description
OpenClaw (npm package 'openclaw') before 2026.8.1 could send third-party provider credentials to the wrong endpoint. In affected versions, when a third-party provider uses an OpenAI-compatible API and the resolved model metadata lacks a concrete base URL, a pinned session that continues after a model configuration hot reload retains that provider's credential while the OpenAI SDK selects its own default endpoint. A resulting request could disclose the configured third-party provider credential to an unrelated provider endpoint and fail with a misleading authentication error. Operators who observed this condition should rotate the affected credential. The issue is fixed in 2026.8.1.

Executive Summary

OpenClaw before version 2026.8.1 has a vulnerability where third-party provider credentials could be sent to the wrong endpoint. This happens when a third-party provider uses an OpenAI-compatible API and the model metadata lacks a concrete base URL. After a model configuration hot reload, a pinned session retains the provider's credential while the OpenAI SDK switches to its default endpoint, potentially exposing the credential to an unrelated provider.

Detection Guidance

The vulnerability may be detected by monitoring network traffic for unexpected credential disclosures or authentication errors during model hot reloads. Check OpenClaw logs for sessions continuing after model configuration changes without explicit base URLs configured for third-party providers.

Impact Analysis

This vulnerability could lead to unauthorized disclosure of third-party provider credentials. If exploited, an attacker might gain access to sensitive credentials, leading to potential misuse of services or data breaches. Operators should rotate affected credentials immediately if this issue is observed.

Compliance Impact

This vulnerability could result in unauthorized exposure of sensitive data, which may violate compliance requirements under GDPR, HIPAA, or other regulations. Unauthorized credential disclosure could lead to data breaches, triggering legal and regulatory penalties for non-compliance.

Mitigation Strategies
  • Upgrade OpenClaw to version 2026.8.1 or later.
  • Rotate any exposed third-party provider credentials.
  • Explicitly configure base URLs for all third-party providers.
  • Avoid continuing pinned sessions after changing model defaults.
