CVE-2023-23973Network attack vector

Contact creation via forged privileged request

Published Mar 1, 2023 · Updated Apr 28, 2026

CSRF in a3rev Software Contact People 3.7.0 and earlier allows remote attackers to create contacts through a privileged account. The advisory identifies contact creation as the affected action but does not disclose the request handler or missing request-validation operation. Exploitation requires a higher-privileged user to act on attacker-controlled content, after which an unwanted contact is added under the victim's session.
