PyJWT: PyJWK accepts empty HMAC keys, bypassing PyJWT's empty-key validation

Summary A service that verifies HS256 tokens using an empty oct JWK through PyJWK, including a PyJWK obtained from PyJWKSet, can therefore accept attacker-generated tokens as authenticated. PyJWT 2.13.0 rejects an empty HMAC key when it is supplied through the raw str/bytes key path, but accepts...

SUSE CVE-2026-102267

PyJWT is a Python implementation of JSON Web Token standards. Prior to 2.14.0, PyJWT PyJWKClient is affected because redirect destinations are not revalidated against the JWKS trust boundary. This occurs when a configured trusted JWKS endpoint returns an attacker-influenced redirect. As a result,...

GHSA-P4G4-X82P-Q773 PyJWT: Public keys in DER form are accepted as HMAC secrets, bypassing the CVE-2022-29217 guard

Summary HMACAlgorithm.preparekey blocks asymmetric keys from being used as HMAC secrets by searching for text markers only. It looks for -----BEGIN and for an ssh- prefix. The same key in DER form is binary ASN.1 and has neither marker, so it passes the check and is used as an HMAC secret. An...

CVE-2026-91191

The Lantronix G520 Series Cellular Gateway is vulnerable to an improper verification of cryptographic signatures in its update mechanism. During boot, the stock done function disables signature verification in the OPKG configuration before restoring packages from an unsigned feed. Furthermore, th...

CVE-2026-102821

A flaw was found in russh. An authenticated remote attacker can cause a Denial of Service DoS by initiating a Secure Shell SSH key renegotiation without completing it and flooding the server with channel open requests. Because the server continues buffering incoming requests without draining the...

CVE-2026-102824

A flaw was found in russh. The library fails to validate peer public keys during hybrid cryptographic key exchange, accepting an all-zero key. A remote attacker acting as a malicious Secure Shell SSH peer can exploit this flaw during connection negotiation to force the classical encryption...

CVE-2026-102824

The Russh Rust SSH client and server library (prior to version 0.63.0 ) contains a vulnerability in the hybrid ML-KEM 768 and X25519 key exchange implementation. The root cause is a missing zero-point validation in russh/src/kex/hybrid_mlkem.rs, which allows the library to accept an all-zero 32-b...

CVE-2026-102824 Russh: Missing X25519 zero-point validation in hybrid ML-KEM key exchange

Russh is a Rust SSH client and server library. Prior to 0.63.0, the hybrid ML-KEM 768 and X25519 implementation in russh/src/kex/hybridmlkem.rs accepts an all-zero 32-byte peer X25519 public key in both serverdh and computesharedsecret, forcing the X25519 contribution to the combined shared secre...

CVE-2026-77696

A flaw was found in OpenSSL. During SM2 signature generation, variable-time arithmetic operations are performed on secret values, creating an observable timing side-channel. An attacker capable of measuring signature generation times can collect timing data across multiple signing operations, whi...
