CVE-2026-3189Public exploitNetwork attack vector

Authenticated SSRF via unvalidated download URL

Published Feb 25, 2026 · Updated Feb 25, 2026

SSRF in sz-boot-parent 1.3.2-beta allows remote authenticated users to read server-reachable resources through the file download API. The urlDownload method passes the url parameter to new URL(fileUrl).openStream() without validating its protocol, permitting file and network schemes. Exploitation requires oss.accessMode to be non-private and exposes returned resource contents without reported write or code-execution impact.
