CVE-2026-32049

OpenClaw's inbound media downloads could exceed configured byte limits before rejection across multiple channels

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.

  • Package: openclaw (npm)
  • Affected versions: <= 2026.2.21-2 (latest published at triage time)
  • Fixed in: 2026.2.22 (planned next release)

Impact

An attacker could cause elevated memory usage and potential process instability (denial of service) by sending oversized media payloads.
