OpenClaw hardened cron webhook delivery against SSRF

Assigner: GitHub_M
Reserved: 19.02.2026 Published: 21.02.2026 Updated: 21.02.2026

OpenClaw is a personal AI assistant. In versions 2026.2.17 and below, Cron webhook delivery in src/gateway/server-cron.ts uses fetch() directly, so webhook targets can reach private/metadata/internal endpoints without SSRF policy checks. This issue was fixed in version 2026.2.19.
