CVE-2020-5528 describes a cross-site scripting (XSS) vulnerability affecting multiple versions of Movable Type, including Movable Type 7, 6.5, Advanced, and Premium editions. This flaw allows remote attackers to inject malicious web scripts or HTML into the block and rich text editors through specially crafted URLs. Rated as Medium severity (CVSS 6.1), it requires user interaction (UI:R) but can be exploited with low attack complexity (AC:L) over the network (AV:N), potentially leading to limited confidentiality and integrity impacts (C:L/I:L). There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this vulnerability.
