CVE-2023-36809

Advisory

Affected versions of Kiwi TCMS implemented changes to serve all uploaded files as plain text, intending to prevent browsers from executing potentially dangerous files when accessed directly. However, the prior Nginx configuration was flawed, allowing certain browsers like Firefox to occasionally ignore the Content-Type: text/plain header, thus permitting potentially dangerous scripts to be executed.
