Now for attribute context, check if double quotes (") are being filtered by entering x"d3v. If it gets altered to x"d3v, chances are that output is getting properly escaped. If this happens, try doing the same for single quotes (') by entering x'd3v, if it gets altered to x', you are doomed. The only thing you can try is encoding. If the quotes are not being filtered, you can simply try payloads from Awesome Context Breaking section. For javascript context, check which quotes are being used for example if they are doing variable = 'value' or variable = "value" Now lets say single quotes (') are in use, in that case enter x'd3v. If it gets altered to x\'d3v, try escaping the backslash () by adding a backslash to your probe i.e. x\'d3v. If it works use the following payload: \'-alert()// But if it gets altered to x\\\'d3v, the only thing you can try is closing the script tag itself by using </script><svg onload=alert()> For simple HTML context, the probe is x<d3v. If it gets altered to x>d3v, proper sanitization is in place. If it gets reflected as it as, you can enter a dummy tag to check for potential filters. The dummy tag I like to use is x<xxx>. If it gets stripped or altered in any way, it means the filter is looking for a pair of < and >.
