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...

Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.3.25 Description OpenClaw versions prior to 2026.3.25 are susceptible to a denial of service. The software parses JSON request bodies before validating webhook signatures, which allows unauthenticated attackers ...

BIT-NODE-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...

CVE-2026-29772

Astro is a web framework. Prior to version 10.0.0, Astro's Server Islands POST handler buffers and parses the full request body as JSON without enforcing a size limit.
