CVE-2026-34986

CVE-2026-34986 affects the Go JOSE library. Prior to versions 4.1.4 and 3.0.5, decrypting a JWE object can cause a panic when the alg field indicates a key-wrapping algorithm (any ending with KW, except A128GCMKW/A192GCMKW/A256GCMKW) and encrypted_key is empty. The panic occurs in cipher.KeyUnwra...

CVE-2026-34986

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 4.1.4 and 3.0.5, decrypting a JSON Web Encryption JWE object will panic if t...

GHSA-78H2-9FRX-2JM8 Go JOSE Panics in JWE decryption

Impact Decrypting a JSON Web Encryption JWE object will panic if the alg field indicates a key wrapping algorithm one ending in KW, with the exception of A128GCMKW, A192GCMKW, and A256GCMKW and the encryptedkey field is empty. The panic happens when cipher.KeyUnwrap in keywrap.go attempts to...

Uncaught Exception

Overview Affected versions of this package are vulnerable to Uncaught Exception in the cipher.KeyUnwrap function when decrypting a JSON Web Encryption JWE object with a key wrapping algorithm ending in 'KW', except for 'A128GCMKW', 'A192GCMKW', and 'A256GCMKW' and the encryptedkey field is empty...

SUSE CVE-2026-33204

SimpleJWT is a simple JSON web token library written in PHP. Prior to version 1.1.1, an unauthenticated attacker can perform a Denial of Service via JWE header tampering when PBES2 algorithms are used. Applications that call JWE::decrypt on attacker-controlled JWEs using PBES2 algorithms are...

CVE-2026-33204

A flaw was found in SimpleJWT, a PHP library for JSON Web Tokens. An unauthenticated attacker can exploit this vulnerability by tampering with JSON Web Encryption JWE headers when Password-Based Key Derivation Function 2 PBES2 algorithms are in use. This can lead to a Denial of Service DoS if an...
