@JoyeeCheung @TechAtBloomberg 👏

This must've been one of the most challenging things I've worked on in a while. Thanks @TechAtBloomberg for sponsoring my work on this, and everyone who helped shipping a fix in time!

The fix has been merged into V8 and can be enabled via `v8_enable_seeded_array_index_hash`. It has been shipped to Node.js v25, v24, v22, and v20 via the March 2026 security release. Upgrade now to to protect your applications from this vulnerability!

With a security release deadline to meet, we interleaved the hash exploration, statistical evaluation, V8 implementation, and performance testing during the development. More details in the blog post.

Can a hash be both HashDoS resistant *and* quickly reversible? That's the puzzle we had to tackle in V8 for the March 2026 Node.js security release. For details, check out our blog post (with the math for the curious!) For a quick overview, 🧵 below nodejs.org/en/blog/vulner…

⚠️ Security releases are now available for the 25.x, 24.x, 22.x, 20.x Node.js release lines. Please see the blog post for additional details: nodejs.org/en/blog/vulner…

⚠️ Security release pre-alert: We will release new versions of 20, 22, 24, 25 release lines on or shortly after 24th March, 2026 in order to address: * 2 high severity issues * 5 medium severity issues * 2 low severity issues nodejs.org/en/blog/vulner…
