CVE-2023-30019Network attack vector

Internal resource access via unchecked source addresses

Published May 8, 2023 · Updated Feb 13, 2025

SSRF in imgproxy before 3.15.0 allows remote attackers to retrieve data from network addresses reachable by the image server. Before the fix, the source-image download transport accepted an imageURL and connected without rejecting loopback or link-local destination addresses. An unauthenticated processing request can therefore use the server's network position to read responses from otherwise unreachable services; integrity and availability impacts are not reported.
