OpenClaw: Microsoft Teams media fetch paths bypass shared SSRF guard model

  • Disclosed: 03.03.2026
  • Updated: 11.10.2026 10:22

Impact

Microsoft Teams media handling used mixed fetch paths for Graph metadata/content and attachment auth-retry flows. Some paths bypassed the shared SSRF guard model and created inconsistent host/DNS enforcement across redirect/fetch hops.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published vulnerable version: 2026.2.25
  • Affected range: <= 2026.2.25
  • Planned patched version for next release: 2026.2.26

Technical Details

The Microsoft Teams attachment/media code previously relied on plugin-local fetch behavior in parts of the flow, instead of uniformly using shared guarded fetch logic with pinned DNS + policy checks. This could allow policy drift and SSRF boundary inconsistency between channel/plugin paths.

The fix unifies this path by:

  • routing Microsoft Teams Graph message/hosted-content/attachment fetches through shared SSRF-guarded fetch paths,
  • routing auth-scope fallback attachment downloads through the same guarded policy model,
  • centralizing hostname-suffix allowlist policy helpers in plugin-sdk so channel/plugins use the same allowlist normalization and policy construction behavior.
