CVE-2026-110874 Details
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.
A PHP object injection vulnerability has been identified in Dolibarr versions prior to 23.0.4. The issue resides in the 'jsonOrUnserialize()' function within 'functions.lib.php', where 'unserialize()' is called without restrictions on classes, allowing for the injection of serialized objects. This vulnerability can be exploited by attackers who can write to stored extrafields, export configurations, or blocked log entries, potentially leading to unauthorized code execution or manipulation of files.
Users can upgrade to Dolibarr version 23.0.4 or later, where this vulnerability has been fixed.
