CVE-2026-100528

OpenClaw before 2026.8.1 Credential Disclosure via Provider Endpoint

Published Sep 26, 2026 CVSS 4.0 · 5.9 Medium EPSS < 1% KEV · Not listed
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.
