More relevant than ever: you can find my other social profiles on my website: lcas.dev. I hope to see many of your there soon! (no direct links because the almighty overlord blocks them now)

I am very proud of the team for the runtime level mitigation we rolled out to @deno_land Deploy for this. It's very precise, very fast, and way less prone to false positives than a WAF based block. All React reversions are safe when running on Deno Deploy. Vertical integration!

There is critical vulnerability in React Server Components disclosed as CVE-2025-55182 that impacts React 19 and frameworks that use it. A fix has been published in React versions 19.0.1, 19.1.2, and 19.2.1. We recommend upgrading immediately. react.dev/blog/2025/12/0…

Full transparency: someone from both @ncsc_nl and the incident response team from @Logius_minbzk reached out to me and are working on resolution. The system does work after all - report issues folks! And thanks folks :)

I sent a CVD report to @ncsc_nl's CERT, and they are being wholly unhelpful. Do I know anyone that works on DigiD or other cyber security stuff at @Rijksoverheid? Is there a report channel for DigiD directly that bypasses NCSC?
