Summary

CVE-2023-46945 is a critical-severity SSRF (CWE-918) vulnerability in Qd-Today Qd. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 15.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 AC-4 (Information Flow Enforcement) and SC-7 (Boundary Protection).

Deeper analysis

CVE-2023-46945 is a server-side request forgery (SSRF) vulnerability, classified under CWE-918, affecting QD version 20230821. The issue arises from a crafted request that enables attackers to manipulate the server into initiating unintended connections, earning a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N). It was published on 2026-04-08T17:17:01.010.

Unauthenticated attackers can exploit this vulnerability remotely over the network with low complexity and no user interaction required. By sending a specially crafted request to an affected QD instance, they can achieve high impacts on confidentiality and integrity, such as forcing the server to access internal resources or services that would otherwise be inaccessible from external networks.

Mitigation details are available in the referenced advisories, including a GitHub Gist at https://gist.github.com/kurokoleung/5b36b2013a54adadcce79967d3e4f056 and the QD project page at https://qd-today.github.io/qd/.

Why these techniques?

SSRF in a public-facing application directly enables remote exploitation of the server to access internal resources (T1190).
