This article provides guidelines for writing effective vulnerability reports. It emphasizes the importance of clearly highlighting the vulnerability, providing a detailed breakdown, explaining the potential impact, including a coded Proof of Concept (POC), and offering straightforward mitigation recommendations. Following these guidelines may increase the chances of the report being labeled as 'selected for report' and potentially increase rewards.
Did you know that issues labeled as "selected for report" can potentially increase your rewards? Naturally, you’re probably now thinking “how can I get my finding labeled as such? What makes a good write-up?” Lucky for you, we’re going to showcase a good example of just that.
