CVE-2026-53939
A flaw was found in cjose. When encrypting a JSON Web Encryption JWE object using AES-CBC-HMAC algorithms, the library initializes the encryption key with all-zero bytes instead of generating a secure random key. As a result, an attacker who intercepts the encrypted message can decrypt sensitive...
Insecure Randomness
Overview Affected versions of this package are vulnerable to Insecure Randomness due to the HKDFexpand and EVPHPKECTXexport functions returning a zero-filled byte array on failure, which is then used as key material for AEAD encryption. An attacker can predict and exploit the deterministic,...

CVE-2025-13470
In RNP version 0.18.0 a refactoring regression causes the symmetric session key used for Public-Key Encrypted Session Key PKESK packets to be left uninitialized except for zeroing, resulting in it always being an all-zero byte array. Any data encrypted using public-key encryption in this release...

golang-fips: Golang FIPS zeroed buffer
A vulnerability was found in Golang FIPS OpenSSL. This flaw allows a malicious user to randomly cause an uninitialized buffer length variable with a zeroed buffer to be returned in FIPS mode. It may also be possible to force a false positive match between non-equal hashes when comparing a trusted...

NATS Server Security Vulnerability
NATS Server is an open source messaging system. The system is primarily used for cloud-native applications, IoT messaging, and microservice architectures. A security vulnerability exists in NATS Server versions 2.10.0 through 2.10.3, and nkeys versions 0.4.0 through 0.4.5, which stems from the...
Junos OS: Short MacSec keys may allow man-in-the-middle attacks.
If all 64 digits of the connectivity association name CKN key or all 32 digits of the connectivity association key CAK key are not configured, all remaining digits will be auto-configured to 0. Hence, Juniper devices configured with short MacSec keys are at risk to an increased likelihood that an...
RUSTSEC-2017-0001 scalarmult() vulnerable to degenerate public keys
The scalarmult function included in previous versions of this crate accepted all-zero public keys, for which the resulting Diffie-Hellman shared secret will always be zero regardless of the private key used. This issue was fixed by checking for this class of keys and rejecting them if they are us...
