Imgur

SIMPLE RULES

• Do not make any information public until the issue has been resolved.
• Make a good faith effort to avoid interruption or degradation of our services .
• Do not access or modify data that does not belong to you - create a free account to test with.
• Making many substantially similar reports will only be eligible for one bounty award and marked as duplicate. For example, the same vulnerability reported across multiple subdomains. Please consolidate these issues into a single report.
• Please try to limit the number of times you follow up on a report. Making daily comments only adds to our workload and makes turnaround time longer for everyone.
• This bounty program is only concerned with security-related bugs, please e-mail [email protected] for all other bugs.
• If your report is related to an advertiser on our site, please refer to https://help.imgur.com/hc/en-us/articles/205107685-Bad-Ads for further guidance.

EXCLUSIONS

The following conditions are out of scope for the vulnerability disclosure program. Any of the activities below will result in disqualification from the program permanently.

• Public release of information before submission through Hackerone.
• Bugs coming from third party softwares in use by imgur. e.g. store.imgur.com and help.imgur.com
• Physical attacks against Imgur employees, offices, and data centers.
• Any vulnerability obtained through the compromise of a Imgur customer or employee accounts. If you need to test a vulnerability, please create a free account.
• Social engineering of Imgur employees, contractors, vendors, or service providers.

• Imgur has global rate limiting that might not be apparent with low testing volume. Please refrain from reporting issues that require no rate limit to be in place.
• CSRF - we are aware of many parts of the site that are vulnerable to CSRF and are currently working on a site wide fix. After the fix goes out, we'll remove this exclusion.
• Open redirects. We currently are not addressing this issue, but hope to in the future. We will mark these as "Informative".
• OAuth misconfiguration and email signup merging can lead to issues - we are aware that there is a potential problem and are already working on a fix for all platforms.
