CVE-2025-52196Network attack vector

Information disclosure via iframe preview SSRF

Published Dec 16, 2025 · Updated Dec 16, 2025

SSRF in CTERA Portal 8.1.1417.24 allows remote attackers to read responses from arbitrary HTTP requests through document preview. The preview backend renders an uploaded HTML file and follows an attacker-controlled iframe URL without restricting its destination, then returns the fetched response in the preview. No authentication or user interaction is required; reachable internal APIs and storage services can be read through the portal, while integrity and availability impacts are not reported.
