SiYuan v3.1.12 before v3.8.6 Denial of Service via getDynamicIcon Template
SiYuan v3.1.12 before v3.8.6 fails to restrict the Sprig template function map in the /api/icon/getDynamicIcon content parameter, allowing resource exhaustion. A publish reader, or anyone when publish auth is disabled, can use uncapped functions like until to OOM-kill the kernel with one request.
