CVE-2026-29609 (GCVE-0-2026-29609)

Vulnerability from cvelistv5 – Published: 2026-03-05 22:00 – Updated: 2026-03-09 20:37

Title

OpenClaw < 2026.2.14 - Denial of Service via Unbounded URL-backed Media Fetch

Summary

OpenClaw versions prior to 2026.2.14 contain a denial of service vulnerability in the fetchWithGuard function that allocates entire response payloads in memory before enforcing maxBytes limits. Remote attackers can trigger memory exhaustion by serving oversized responses without content-length headers to cause availability loss.
