We would like to thank everyone who submits valid reports that help us improve the security of Newsletters, Email Marketing, SMS and Popups by Omnisend. However, only those that meet the following eligibility requirements may receive a monetary reward for vulnerabilities found in the Newsletters, Email Marketing, SMS and Popups by Omnisend source code.
You must be the first reporter of a vulnerability.
The vulnerability must be a qualifying vulnerability (see below).
Any vulnerability found must be reported no later than 24 hours after discovery and exclusively through patchstack.com.
You must avoid tests that could cause degradation or interruption of our service (refrain from using automated tools, and limit your requests per second). If you over do it, your IP address might be throttled or even (temporarily) blocked to protect our infrastructure. See how.
Reports on vulnerabilities are examined by our security analysts - our analysis is always based on worst case exploitation & the business criticality of the vulnerability, as is the reward we pay.
