Kerentanan Deserialization of Untrusted Data pada opencats. Skor CVSS 3.1 9.8 (Critical) menurut NVD.

Deskripsi (NVD)

OpenCATS through 0.9.5-3 unsafely deserializes index.php?m=activity requests, leading to remote code execution. This occurs because lib/DataGrid.php calls unserialize for the parametersactivity:ActivityDataGrid parameter. The PHP object injection exploit chain can leverage an __destruct magic method in guzzlehttp.
