Is ConcertPal: Your Ticket to Concert Savings safe?

Low risk

ConcertPal removes Ticketmaster framing protections to load hidden pages and reuse the tmpt cookie.

ConcertPal installs a browser rule that removes X-Frame-Options, Frame-Options, and Content-Security-Policy headers from Ticketmaster pages before opening an offscreen iframe. It uses that hidden page to collect the tmpt cookie, stores it locally, and sends it with requests to Ticketmaster's offeradapter API alongside embedded API credentials.
