In Node.js/V8, HashDoS vulnerabilities tend to center around misconfigurations that lead to unseeded hashes or hashes seeded by a constant value. For an early history of HashDoS vulnerabilities in Node.js/V8 and their mitigations, check out this V8 blog post. A more recent example is CVE-2025-27209, reported by Mate Marjanović and addressed in Node.js's July 2025 security release: during V8's switch to rapidhash, a configuration gap left the constants used by rapidhash hard-coded in V8 without seeding. To mitigate this, Node.js temporarily reverted back to a seeded hash in its copy of V8. Later, Gus Caplan from Deno ported rapidhash's secret generation code to V8 and wired it up to seed the constants used by rapidhash at runtime, which became the eventual mitigation that shipped in newer versions of Node.js. The generation of rapidhash secrets turned out to be important to our later design for the seeded integer hash, which we will discuss below.
