CVE-2018-0114

CVE-2018-0114 Exploitation of a vulnerability in Cisco's node-jose, a JavaScript library created to manage JWT. This vulnerability in Cisco's node-jose allows an attacker to forge malicious tokens. JWT allows users to embed public keys using the jwk value inside the header of the token. However,...

Go JOSE: DoS when parsing JWKs that contain RSA keys

Summary A crafted RSA key inside a JWK can cause operations that parse JWKs to consume excess CPU. Details go-jose does not check for bounds on RSA modulus and primes before validating them. Values are passed directly to crypto/rsa.PrivateKey.Validate. On Go 1.24+, this takes cubic time complexit...

CVE-2026-65628

josejwk:sharedsecret/2 exposed in Elixir as JOSE.JWK.sharedsecret/2 derives an ECDH shared secret from two JWKs. Its first function clause only matches when both JWKs carry the same key type kty module, and its fallback clause re-invokes itself as sharedsecretfromYourJWK, fromMyJWK. Because from/...

CVE-2026-116587 Go JOSE: DoS when parsing JWKs that contain RSA keys

Go JOSE provides an implementation of the Javascript Object Signing and Encryption set of standards in Go, including support for JSON Web Encryption JWE, JSON Web Signature JWS, and JSON Web Token JWT standards. Prior to 4.1.6, go-jose parses attacker-controlled RSA modulus and prime values from...

CVE-2026-65632
