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...

UBUNTU-CVE-2026-21713

A flaw in Node.js HMAC verification uses a non-constant-time comparison when validating user-provided signatures, potentially leaking timing information proportional to the number of matching bytes. Under certain threat models where high-resolution timing measurements are possible, this behavior...

CVE-2026-21711

A flaw in Node.js Permission Model network enforcement leaves Unix Domain Socket UDS server operations without the required permission checks, while all comparable network paths correctly enforce them. As a result, code running under --permission without --allow-net can create and expose local IP...

CVE-2026-21710

A flaw in Node.js HTTP request handling causes an uncaught TypeError when a request is received with a header named proto and the application accesses req.headersDistinct. When this occurs, dest"proto" resolves to Object.prototype rather than undefined, causing .push to be called on a non-array...

CVE-2026-21717

CVE-2026-21717 affects multiple Node.js releases (nodejs20, nodejs22, nodejs24, nodejs25) with the root cause in V8 string hashing causing integer-like strings to hash to their numeric value, enabling hash collisions that can degrade Node.js process performance. Public details show nodejs24 is af...
