Please note: This program does not allow disclosure. You may not release information about vulnerabilities found in this program to the public.

Overstock.com encourages you to responsibly report any security issues you're able to identify on Overstock.com!


For the initial prioritization/rating of findings, this program will use the Bugcrowd Vulnerability Rating Taxonomy. However, it is important to note that in some cases a vulnerability priority will be modified due to its likelihood or impact. In any instance where an issue is downgraded, a full, detailed explanation will be provided to the researcher - along with the opportunity to appeal, and make a case for a higher priority.

This program only awards points for VRT based submissions.

Target info:


Please note this is a production environment.

  • Do not conduct tests against customer accounts (e.g. accounts you do not expressly own)
  • Do not conduct tests that will impact the performance of the environment
  • If you feel you have found a security issue, but testing will impact the environment, please submit the issue and contact support@bugcrowd.com
  • This is a production site, so please avoid copious amounts of scanner activity
  • If your IP address gets banned for excessive scanning, please wait 4 hours to be unbanned, if you still experience issues please email support@bugcrowd.com (which is one more reason to be judicious with the amount of total requests you're sending while testing on ALL targets)
