Common Vulnerability Scoring System (CVSS) is a well-established standard for an evaluation of vulnerability criticality of Information and Communication Technology (ICT) infrastructure. An analysis was performed aimed at selected vulnerabilities, considering their base score, temporal score, reporting and exploit availability through time. Data obtained using publicly available sources, including National Vulnerability Database (NVD), ExploitDB and AttackerKB, reports and social media posts, were analyzed using a dedicated python application. Obtained results contribute to the basic research seeking to establish automated temporal score calculation that allows to assess the likelihood of exploitation for a given vulnerability.
