Kuza55 pointed me to yet another XSS vulnerability archive today. Seems that there are more of these popping up recently. This one is a little better than most, although it only has a handful listed, compared to the 1000+ listed on sla.ckers.org.
It appears to be mostly looking at international and .gov sites so far (with an emphasis on pagerank or importance). It also has metrics to track who is the top discoverer of XSS vulnerabilities. I’m just waiting for whomever is going to scrape the “so it begins” thread on sla.ckers.org and completely owns the top poster, or uses a series of google dorks to find hundreds or thousands of vulnerable XSSs. I’ve always thought ranking the number of vulnerabilities posted was rather silly given the sheer volume of vulnerable sites out there.
