openclawnpmDescription
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update openclaw to 2026.2.22 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-32037 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2026-32037 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2026-32037. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-32037 in your dependencies?
O3 Security finds CVE-2026-32037 across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
