GHSA-rxxp-482v-7mrh — high GitHub Advisory (CVE-2026-32049) in npm/openclaw

Description

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: 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.
