Advisories: DoraCMS <= 3.1 UEditor Remote Image Fetch SSRF Severity: Medium Date: 2/10/2026 Affecting: DoraCMS <= 3.1 References: - CVE-2026-25870 - GitHub Issue - DoraCMS Product Webpage Credit: Lennon Chia Description: DoraCMS version 3.1 and prior contains a server-side request forgery (SSRF) vulnerability in its UEditor remote image fetch functionality. The application accepts user-supplied URLs and performs server-side HTTP or HTTPS requests without sufficient validation or destination restrictions. An attacker can abuse this behavior to induce the server to issue outbound requests to arbitrary hosts, enabling internal network scanning and denial of service through resource exhaustion.
