Operationally, ranked in the top 0.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2023-41425 is a cross-site scripting vulnerability affecting Wonder CMS versions 3.2.0 through 3.4.2. The flaw resides in the installModule component and is triggered when a crafted script is uploaded, enabling execution of arbitrary code in the context of a victim's browser session.
A remote attacker can exploit the issue without authentication by supplying a malicious upload that executes when a user interacts with the affected component. Successful exploitation yields limited impacts on confidentiality and integrity while leaving availability unaffected, consistent with the reported CVSS vector requiring user interaction and producing a changed scope.
Public references include the vendor site along with exploit artifacts hosted on GitHub Gists and Packet Storm that demonstrate the upload-based attack vector. The associated EPSS score remains elevated near 0.91 with negligible movement between its recorded peak and current values.
