Three vulnerabilities patched in the /export.ics route:
- esc() now handles bare \r and CRLF sequences — the previous regex only
matched \n, leaving \r intact and allowing CRLF injection via \r\n
- reservation DESCRIPTION field was built from unescaped user data
(type, confirmation_number, notes, airline, flight/train numbers,
airports) and written raw into ICS output; now passed through esc()
- Content-Disposition filename used ICS escaping instead of HTTP header
sanitization; replaced with a character allowlist to prevent " and
\r\n injection into the response header
