This tweet highlights a valuable resource for learning Cross-Site Scripting (XSS) deeply: PortSwigger XSS Labs, which contains over 30 labs ranging from simple to very advanced levels. Each lab explains different contexts of XSS, and completing all labs changes the learner's perspective on XSS entirely. The tweet also prompts the audience to share their experiences about the hardest WAF bypass they have encountered, inviting engagement and sharing of knowledge in the bug bounty and web security communities.
