Quick assessment

Affected
Dolibarr dolibarr
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Dolibarr 23.0.4 之前的版本中，functions.lib.php 文件里的 jsonOrUnserialize() 函数存在 PHP 对象注入漏洞。该函数在 json_decode() 失败时会调用 unserialize()，但未对反序列化类进行限制。能够写入存储的额外字段、导出配置或受阻日志条目的攻击者可以植入序列化对象，从而触发 gadget 链以实现代码执行或文件操纵。
