CVE-2026-10771Public exploitNetwork attack vector

Unauthenticated SSRF via unchecked QR code URL

Published Jun 3, 2026 · Updated Jun 3, 2026

SSRF in CRMEB Java 1.4 allows remote attackers to send arbitrary HTTP requests through the unauthenticated base64 QR code endpoint. POST /api/front/qrcode/base64 passes its url parameter through getBuffer directly to RestTemplate.getForEntity without validation. No credentials are required because the route is excluded from the front-token interceptor; responses expose the reachability of internal services.
