(post data fuzzing)

Fuzz post data:

vaf.exe -w example_wordlists\short.txt -u https://jsonplaceholder.typicode.com/posts -m post -sc 201 -pd "{\"title\": \"[]\"}"

Fuzz GET URLs

vaf.exe -w example_wordlists\short.txt -u https://example.org/[] -sf .html

• Add a trailing , in the suffixes or prefixes argument to try the word without any suffix/prefix like this: -pf .php, or -sf .php,
• Use -pif with a bunch of xss payloads as the wordlist to find XSS
• Make an issue if you want to suggest a feature
