Affected: Homebrew: openclaw-cli

## Summary

NOTE: This only affects deployments that enable the optional MS Teams extension (Teams channel). If you do not use MS Teams, you are not impacted.

When OpenClaw downloads inbound MS Teams attachments / inline images, it may retry a URL with an `Authorization: Bearer <token>` header after receiving `401` or `403`.

Because the default download allowlist uses suffix matching (and includes some multi-tenant suffix domains), a message that references an untrusted but allowlisted host could cause that bearer token to be sent to the wrong place.

## Affected Packages / Versions

- Package: `openclaw` (npm) - Vulnerable: `<= 2026.1.30` - Patched: `>= 2026.2.1`

## Fix

- Fix commit: `41cc5bcd4f1d434ad1bbdfa55b56f25025ecbf6b` - Upgrade to `openclaw >= 2026.2.1`

## Workarounds

- If you do not need MS Teams, disable the MS Teams extension. - If you must stay on an older version, ensure the auth host allowlist is strict (only Microsoft-owned endpoints that require auth) and avoid wildcard or broad suffix entries.

 https://db.gcve.eu/vuln/cve-2026-28481 CVE-2026-28481 — OpenClaw < 2026.2.1 - Bearer Token Leakage via MS Teams Attachment Downloader Suffix Matching 2026-09-30T05:48:31.375728+00:00

Affected: OpenClaw

OpenClaw versions 2026.1.30 and earlier, contain an information disclosure vulnerability, patched in 2026.2.1, in the MS Teams attachment downloader (optional extension must be enabled) that leaks bearer tokens to allowlisted suffix domains. When retrying downloads after receiving 401 or 403 responses, the application sends Authorization bearer tokens to untrusted hosts matching the permissive suffix-based allowlist, enabling token theft.
