What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

Dolibarr before 23.0.4 contains a PHP object injection vulnerability in jsonOrUnserialize() in functions.lib.php, which calls unserialize() without class restrictions when json_decode() fails. Attackers able to write stored extrafields, export configurations or blocked log entries can plant serialized objects that trigger gadget chains for code execution or file manipulation.
