To clarify, why is being able to display an alert a massive security flaw in this context?
- retube 5y agoThe alert itself is harmless, but demonstrates that arbitrary javascript - which could certainly not be harmless - can be injected into the page.
- mynameismon 5y agoIt's not the ability to display alerts that is concerning, but rather, the ability to run untrusted Javascript. This was a proof of concept that showed that it has a serious XSS vulnerability
- seedie 5y agoFor detailed information on what XSS is, how it can be exploited and prevented have a look at the OWASP XSS description https://owasp.org/www-community/attacks/xss https://owasp.org/www-community/attacks/xss
