Yes but Flash vulnerabilities are incremental vulnerabilities. So just counting high severity vulnerabilities, the chart is IE: 314. IE with Flash: 483. Chrome: 154: Chrome with Flash: 323. Firefox: 86. Firefox with Flash: 255. And of course, you can add a third column for Java and a fourth column for browser with Flash and Java. I have no idea what their bugs-per-line-of-code are, perhaps they have the finest code on the planet. But from a surface area perspective, installing Flash makes you more vulnerable, period. And it really is not necessary, whereas it’s not like you can browse the web in pure Flash and not install a browser.
