OpenClaw's MSTeams attachment redirect handling could bypass configured media host allowlists
Summary
In OpenClaw MSTeams media download flows, redirect handling could bypass configured mediaAllowHosts checks in specific attachment paths. Redirect chains were not consistently constrained to allowlisted targets before accepting fetched content.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
<= 2026.2.21-2(latest published at triage time) - Fixed in:
2026.2.22(planned next release)
Impact
Attackers able to supply or influence attachment URLs could force redirect chains to non-allowlisted targets, weakening SSRF boundary controls for MSTeams media ingestion.

Release Process Note
