Security and Exploit Reports

Found a hole in Tumblr's websites or apps? If you've discovered an exploit that could jeopardize users' blogs, expose their personal information, or allow any other nefarious activity to occur, please tell us about it in the form below.

If your report is not security related such as a forgotten password, inability to access your account, removing images from blogs, etc. - please submit your inquiry to Tumblr Support instead; otherwise, we may not be able to process your request.
