CVE-2020-23595Public exploitNetwork attack vector

Privilege escalation via site-model request forgery

Published Aug 11, 2023 · Updated Oct 9, 2024

Cross-site request forgery in YzmCMS 5.6 allows remote attackers to escalate privileges and access sensitive information through sitemodel/add.html. The public record identifies the affected endpoint but does not disclose the request fields or the specific missing server-side CSRF check. A logged-in user must be induced to submit the crafted request, after which the attacker gains elevated access and exposure of application data.
