Security and Exploit Reports
Found a hole in Tumblr's websites or apps? If you've discovered an exploit that could jeopardize user's blogs, expose their personal information, or allow any other nefarious activity to occur, please tell us about it in the form below.
You can learn more about our Bug Bounty program here.
This form isn't for minor bugs and other non-security support issues, by the way. Please report those to firstname.lastname@example.org.
