nodejs: v8: Node.js: Denial of Service via V8 string hashing mechanism due to predictable hash collisions

A flaw was found in V8's string hashing mechanism within Node.js. A remote attacker can exploit this vulnerability by crafting requests containing integer-like strings. These specially crafted strings cause predictable hash collisions in V8's internal string table, particularly when processed by...

UBUNTU-CVE-2026-21717

A flaw in V8's string hashing mechanism causes integer-like strings to be hashed to their numeric value, making hash collisions trivially predictable. By crafting a request that causes many such collisions in V8's internal string table, an attacker can significantly degrade performance of the...

Node.js: HashDoS in V8

The V8 release used in Node.js v24.0.0 changed how string hashes were computed using rapidhash. This implementation reintroduced the HashDoS vulnerability, where an attacker who could control the strings to be hashed could generate many hash collisions without knowing the hash-seed...

CVE-2017-15428

Insufficient data validation in V8 builtins string generator could lead to out of bounds read and write access in V8 in Google Chrome prior to 62.0.3202.94 and allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page...
