openclawnpmDescription
Summary
OpenClaw did not consistently enforce configured inbound media byte limits before buffering remote media in several channel ingestion paths. A remote sender could trigger oversized downloads and memory pressure before rejection.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected versions:
<= 2026.2.21-2(latest published at triage time) - Fixed in:

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-2026-32049 is resolved across your whole dependency graph.
Workarounds
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
