CVE-2023-6853Public exploitNetwork attack vector

Authenticated SSRF via unchecked path destination

Published Dec 16, 2023 · Updated May 7, 2025

SSRF in kalcaddle KodExplorer 4.51.03 and earlier allows remote authenticated users to issue server-side requests via a crafted path. The officeLive plugin's index function uses the untrusted path argument as a request destination without adequate destination validation. A low-privileged authenticated account is required, and the resulting request can reach resources available to the server rather than the client.
