CVE-2021-28544 is a medium-severity vulnerability affecting Apache Subversion (SVN) servers, including those used by Apple, Debian, and Fedora. It allows authenticated users to discover 'copyfrom' paths of protected resources, revealing the origin of copied files even if the original path should be hidden by authorization rules. The attack is network-based and low complexity, but only exposes the path, not its contents, resulting in a low confidentiality impact. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
