What is CVE-2020-10964?

A security issue has been identified in Serendipity versions before 2.3.4 that allows remote attackers to execute arbitrary code. This vulnerability arises due to the handling of filenames during the renaming process, specifically when a filename ends with a dot. An attacker could exploit this weakness by renaming a file to have a .php extension, potentially leading to unwanted code execution on affected systems.
