NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs24-docs package and not the nodejs24-docs package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

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 process.

The most common trigger is any endpoint that calls JSON.parse() on attacker-controlled input, as JSON parsing automatically internalizes short strings into the affected hash table.

This vulnerability affects 20.x, 22.x, 24.x, and 25.x.
