The 10 Most Impactful Types of Vulnerabilities for Enterprises TodayManaging system vulnerabilities is one of the old est - and most frustrating - security challenges that enterprise defenders face. Every software application and hardware device ships with intrinsic flaws - flaws that, if critical enough, attackers can exploit from anywhere in the world. It's crucial that defenders take stock of what areas of the tech stack have the most emerging, and critical, vulnerabilities they must manage. It's not just zero day vulnerabilities. Consider that CISA's Known Exploited Vulnerabilities (KEV) catalog lists vulnerabilitlies in widely used applications that are "actively exploited," and most of them are flaws that were discovered several years ago and have been fixed. There are also emerging vulnerabilities in 5G networks, cloud infrastructure, Edge applications, and firmwares to consider.

In general, providing an input with an apostrophe should be considered valid, even if the backend uses this value in an SQL query (as the real data being search may have such values, e.g. Name: O'Neill). If I include the text "<grin>" with-in some online forum post/comment, it shouldn't be rejected/removed for no-HTML input fields, but be treated as verbatuim text that is properly escaped in output HTML.
Input validation should normally only be done for specific business logic (e.g. usernames are limited to ASCII letters/numbers and must start with a letter), or general sanity checks (e.g. only ASCII; only valid UTF-8 encoded strings; doesn't contain invalid UNICODE composed sequences; no embedded NUL characters [when using length specified strings]).
