CVE-2025-27209
critical
Description
The V8 release used in Node.js v24.0.0 has changed how string hashes are computed using rapidhash. This implementation re-introduces the HashDoS vulnerability as an attacker who can control the strings to be hashed can generate many hash collisions - an attacker can generate collisions even without knowing the hash-seed. While the V8 team does not classify this as a security vulnerability, the Node.js project considers it one due to its potential impact in real-world scenarios. Impact: Thank you, to sharp_edged for reporting this vulnerability and thank you targos for fixing it.
