python-pyjwt: PyJWT: Authentication bypass due to forged JSON Web Tokens

A flaw was found in PyJWT, a Python library for JSON Web Token JWT implementation. When decoding JWTs, the library fails to validate the use of JSON Web Keys JWK in the HMAC algorithm while also supporting asymmetric algorithms. This allows a remote attacker to use the issuer's public key as the...

CVE-2026-18754 Hardcoded Cryptographic Key on GV-AS1620 Controller Firmware (GV-Cloud)

The product firmware contains an embedded, static RSA private key utilized by the Lighttpd web server for TLS termination. Exposure of this private key allows malicious actors to breach the confidentiality and integrity of HTTPS communications, enabling traffic decryption and server spoofing...
