CVE-2026-10239Public exploitNetwork attack vector

Stored SSRF via unvalidated Word image URL

Published Jun 1, 2026 · Updated Jun 1, 2026

Stored SSRF in JeecgBoot 3.9.0 through 3.9.2 allows remote authenticated users to reach internal services via Word templates. The edit endpoint stores an attacker-controlled image URL, and WordUtil.addImage checks only its HTTP scheme before opening the connection during document download. Low-privileged access and a later template download are required; successful requests can probe internal hosts or read reachable metadata.
