——19A Broken or Risky Cryptographic Algorithm exists in AnonAddy 0.8.5 via VerificationController.php.12dCVE-2026-453639.1 CRI15.4%
——5ruby-jwt is a Ruby implementation of the RFC 7519 OAuth JSON Web Token standard. Prior to 2.10.3 and 3.2.0, JWT.decode(token, '', true, algorithm: 'HS256') accepts an attacker-forged token because OpenSSL::HMAC.digest('SHA256', '', payload) returns a valid digest under an empty key and no empty-key precondition exists in the HMAC algorithm. The same path is reached when a keyfinder block or key_finder: argument returns an empty string, nil, or an array containing nil for an unknown key, affecting HS256, HS384, and HS512 verification through JWT.decode and JWT::EncodedToken#verify_signature!. This issue is fixed in versions 2.10.3 and 3.2.0.5dCVE-2026-78307.4 HIG12.5%
——4UltraVNC through 1.8.2.2 uses inadequate cryptography in the MS-Logon II authentication scheme (rfbUltraVNC_MsLogonIIAuth). In rfb/dh.cpp the Diffie-Hellman key exchange is performed with parameters that fit in an unsigned 64-bit integer (DH_MAX_BITS controls the prime size). A 64-bit DH key can be broken by Pollard's rho algorithm in under one second on current hardware. Additionally, the private exponent is generated by the rng() function, which multiplies three libc rand() values seeded from time(NULL). With approximately 31 bits of internal state and a time-based seed, the private exponent is recoverable in under a minute by a passive observer. A network attacker who can observe the MS-Logon II handshake (via sniffing, recording, or man-in-the-middle) can derive the shared DH key and decrypt the encapsulated username and password, resulting in full credential disclosure. This affects legacy MS-Logon II connections; MS-Logon III (X25519 + AES-256-GCM) is unaffected.12dCVE-2025-635797.5 HIG10.0%
——3Unauthorized use of Kyocera printers, allows all information stored in the Kyocera address book to be exported. The security measure that encrypts incoming data ian be bypassed with this vulnerability, allowing encrypted data to be decrypted. Passwords and other sensitive information can be obtained. This affects Kyocera Command Center RX TASKalfa 2552ci, TASKalfa 3252ci, TASKalfa 2553ci, TASKalfa 3253ci, TASKalfa 3554ci, TASKalfa 4052ci, TASKalfa 5052ci, TASKalfa 6052ci, TASKalfa 7052ci, TASKalfa 8052ci, TASKalfa 7353ci, TASKalfa 8353ci, TASKalfa 2554ci, TASKalfa 3254ci, TASKalfa 505.10dCVE-2026-49852—9.4%
——3joserfc is a Python library that provides an implementation of several JSON Object Signing and Encryption (JOSE) standards. Prior to 1.6.8, joserfc.jwt.decode accepts attacker-forged HMAC-signed tokens when the caller-supplied verification key is the empty string or None, because HMACAlgorithm.sign and HMACAlgorithm.verify in src/joserfc/_rfc7518/jws_algs.py pass the output of OctKey.get_op_key(...) to hmac.new(...) and OctKey.import_key in src/joserfc/_rfc7518/oct_key.py only emits a SecurityWarning for keys shorter than 14 bytes without rejecting zero-length input. This issue is fixed in version 1.6.8.8hCVE-2024-235649.1 CRI8.7%
——3HCL Aftermarket EPC is affected by Business Logic Vulnerability using which a non valid user of the application can obtain passwords from the server and redirect them to their own email address by manipulating the server's response. The application includes checks in the initial requests to verify the validity of the provided UserId, but similar validation is not applied to Email requests when sending passwords to user emails.3d
