I chained three public V8 ndays against Google v8CTF Chrome build and recovered a real flag. Address oracle → GC stale object → fake array → caged R/W → native leak → JSPI/JDT stack pivot → ROP. Real V8 sandbox escape. Terrible reliability No $10k 😅 blog.himanshuanand.com/2026/08/i-ha...

Browsers only read the CSP when a page initially loads. This means that adding or modifying a <meta> tag afterward won’t affect or weaken the policy. Additionally, secure sites typically define the CSP in the HTTP header, which browsers enforce immediately and ignore any attempts to override.

Himanshu Anand @noob.bsky.social · 26/02/2025
I had an stupid thought: since a CSP (Content Security Policy) can be implemented using a <meta> tag, what’s stopping JavaScript from rewriting these meta tags to bypass the CSP? I knew it was not possible but why not?
