On case-insensitive filesystems such as Windows NTFS and macOS APFS/HFS+, a request using mixed-case characters can evade these checks and resolve to protected directories on the filesystem.</p>
<h2 id="impact">Impact</h2>
<p>This vulnerability allows an unauthenticated bypass of authorization boundaries for the /admin, /repo, and /data paths, enabling unauthorized reading or execution of protected content.</p>
<h2 id="recommendation">Recommendation</h2>
<p>Upgrade the Algernon web server to version 1.17.10, where this issue has been addressed.</p>
