What Hacker News says?
In the latest episode of my podcast Señors @ Scale, I interviewed Tudor Barbu (Principal Engineer at Lodgify), and he shared this gem from his early engineering days: They had a UI with dropdowns for selecting a date. To make things look clean, they prefixed single-digit days with a zero, so 1 became 01, for dates below 10 (pretty standard) After some data processing, it was discovered that when converting the strin…

Check out the article: http…

HN discussionMost frontend breaches come down to 3 mistakes: unescaped input, weak cookie policies, and trust in client-side validation. Last year, I ran a quick security audit on 12 production SPAs. All 12 were vulnerable to at least one XSS vector. Example: dangerouslySetInnerHTML={{ __html: userBio }} → looks harmless until a crafted payload like <img src=x onerror=alert(1)> sneaks in. Fix: sanitize with DOMPurify, enforce a…
