CVE-2026-48618

A flaw was found in Node.js. This flaw involves a mismatch in how Node.js handles TLS Transport Layer Security hostnames and unicode dot separators during authentication. This mismatch can lead to a wildcard-depth authentication bypass. An attacker could exploit this to bypass intended security...

Improper Verification of Cryptographic Signature

Overview @sigstore/core is a Base library for Sigstore Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature in the preAuthEncoding function. An attacker can bypass type-binding guarantees by substituting characters in payloadType with Unicode varian...

@sigstore/core has DSSE payloadType type-binding failure

Impact The preAuthEncoding function in @sigstore/core uses Node.js 'ascii' encoding when converting the PAE Pre-Authentication Encoding string to bytes. This allows payloadType to be mutated after signing without invalidating the signature, breaking the type-binding guarantee that DSSE is designe...

CVE-2026-49401

Deno is a JavaScript, TypeScript, and WebAssembly runtime. Prior to 2.7.14, Deno's permission system enforces filesystem and execution restrictions by comparing the requested path against the path supplied to --deny-read, --deny-write, --deny-run, or --deny-ffi. On macOS, that comparison was done...
