Lifecycle Timeline
3DescriptionCVE.org
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.
AnalysisAI
OpenClaw versions 2026.1.30 and earlier leak authentication bearer tokens to untrusted domains when the optional MS Teams attachment downloader extension is enabled, due to overly permissive suffix-based domain allowlisting during download retries. An attacker could harvest these tokens from allowed domains to compromise authenticated sessions. No patch is currently available, affecting users of the vulnerable versions.
