Dolibarr before 23.0.4 PHP Object Injection via jsonOrUnserialize()

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.
