——1The HTML5 KVM-over-IP console authenticates with a token returned by the web interface. Weaknesses in token generation may allow an attacker to guess the session token and take control of the KVM session.2dCVE-2026-55889—28.1%
——8XDG Desktop Portal is a desktop integration portal. Prior to version 1.22.1, malicious sandboxed applications can use the FileTransfer.RetrieveFiles method to redirect drag-and-drop and copy-paste data targeted at other applications to itself. Some portals generate tokens which provide access to resources. The sharing of the token transfers access to the resource and is supposed to happen out of band. The tokens were generated with g_random_int or g_uuid_string_random, both of which use GLib's GRand based on the Mersenne Twister PRNG which created a stream of reproducible random numbers. By generating enough tokens, the state of the GRand can be recover and with it, the next tokens can be predictedinsufin. This issue has been patched in version 1.22.1.13dCVE-2026-737944.6 MED3.1%
——1HPE NonStop MODULAR NSJ contains a predictable seed vulnerability in Random Number Generation (PRNG)23dCVE-2026-19396—2.4%
——1A predictable seed in the pseudo-random number generator (PRNG) in the IFTTT pairing token generation of the ASUS RT-BE57 router allows an unauthenticated nearby user to derive the pairing token and read or modify router settings via observed values from an administrator-initiated IFTTT pairing session.Refer to the ' Security Update for ASUS Router Firmware ' section on the ASUS Security Advisory for more information.29dCVE-2026-260187.5 HIG69.3%
——21CoreDNS is a DNS server that chains plugins. Prior to version 1.14.2, a denial of service vulnerability exists in CoreDNS's loop detection plugin that allows an attacker to crash the DNS server by sending specially crafted DNS queries. The vulnerability stems from the use of a predictable pseudo-random number generator (PRNG) for generating a secret query name, combined with a fatal error handler that terminates the entire process. This issue has been patched in version 1.14.2.114dCVE-2025-627105.9 MED9.9%
——3Sakai is a Collaboration and Learning Environment. Prior to versions 23.5 and 25.0, EncryptionUtilityServiceImpl initialized an AES256TextEncryptor password (serverSecretKey) using RandomStringUtils with the default java.util.Random. java.util.Random is a non‑cryptographic PRNG and can be predicted from limited state/seed information (e.g., start time window), substantially reducing the effective search space of the generated key. An attacker who can obtain ciphertexts (e.g., exported or at‑rest strings protected by this service) and approximate the PRNG seed can feasibly reconstruct the serverSecretKey and decrypt affected data. SAK-49866 is patched in Sakai 23.5, 25.0, and trunk.29d
