CVE-2023-51545Network attack vector

Unauthenticated code execution via forged settings deserialization

Published Dec 29, 2023 · Updated Apr 28, 2026

CSRF in ThemeHigh Job Manager & Career 1.4.4 and earlier allows remote attackers to trigger PHP object injection via a forged request. The save_plugin_settings() function accepts settings without valid nonce verification and deserializes attacker-controlled data. Successful exploitation requires an authenticated administrator to follow a malicious link or submit a forged form and can lead to arbitrary code execution.
