CVE-2023-52200Network attack vector

PHP object injection via cross-site request forgery

Published Jan 8, 2024 · Updated Apr 28, 2026

Cross-site request forgery in Repute InfoSystems ARMember 4.0.22 and earlier allows attackers to trigger PHP object injection. The CNA and Patchstack advisory do not disclose the affected endpoint, function, or untrusted value passed to PHP deserialization. Exploitation requires remote attackers to induce an authenticated higher-privileged user to submit a crafted request, while the concrete effect after object injection remains undisclosed.
