Overstock's Vulnerability Disclosure Page!

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

Ratings:

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.

Any domain/property of Overstock not listed in the targets section is out of scope. This includes any/all subdomains not listed above.

Target info:

overstock.com:

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)
