CVE-2026-32049Network attack vector

Gateway disruption via pre-limit media buffering

Published Mar 21, 2026 · Updated Mar 21, 2026

Resource exhaustion in OpenClaw before 2026.2.22 allows remote attackers to disrupt the Gateway with oversized inbound media. Discord, Telegram, Zalo, Microsoft Teams, and BlueBubbles ingestion paths buffered remote attachments before consistently applying configured byte limits. Remote attackers must be able to send media through an enabled affected channel; the reported consequence is elevated memory use and process instability, not data access or modification.
