4N_CURZE has helped us to find and fix some issues on web sites we're protecting. This kind of help is greatly appreciated from a security perspective. This way we can improve ourselves and protect our customers.

More specifically, the completeness of the report and the details to correct the vulnerability were very appreciated. It was precise and clear. With such good writing skills proven by 4N_CURZE, it's easy to send it to developpers in a way they can understand both problematic and solution.

Thanks again in my name.

Caught me having forgotten to entity-encode values when re-displaying an incomplete form submission. While the initial report was all I needed to patch, Rajash considerately provided additional detail without being asked through the openbugbounty comments.
