PYSEC-2026-3779

opensslencrypt versions before 1.4.9 fail to validate encryption status of embedded post-quantum private keys in file metadata. Attackers can craft files with unencrypted embedded PQC keys that decrypt under any password, bypassing authentication and producing attacker-chosen plaintext with false...

CVE-2026-81703 openssl_encrypt before 1.4.9 Authentication Bypass via Unencrypted PQC Key

opensslencrypt versions before 1.4.9 fail to validate encryption status of embedded post-quantum private keys in file metadata. Attackers can craft files with unencrypted embedded PQC keys that decrypt under any password, bypassing authentication and producing attacker-chosen plaintext with false...

PT-2026-82604

Name of the Vulnerable Software and Affected Versions openssl encrypt versions prior to 1.4.9 Description The software fails to validate the encryption status of embedded post-quantum cryptography PQC private keys within file metadata. This allows attackers to create files containing unencrypted...

GHSA-RC6V-5RMX-W5MV arnika is affected by medium-severity issues in UDP rotation, PQC handling, and KMS TLS

Summary Three medium-severity issues in arnika affecting the UDP key-rotation protocol, PQC key file handling, and KMS TLS client. All require specific preconditions to exploit and do not allow direct code execution or immediate key extraction. A self-contained PoC is attached. Details 1 ACK...

Hybrid Quantum Security for IPsec

Quantum Key Distribution QKD offers information-theoretic security against quantum computing threats, but integrating QKD into existing security protocols remains an unsolved challenge due to fundamental mismatches between pre-distributed quantum keys and computational key exchange paradigms. Thi...

Information-Theoretically Secure Quantum Timestamping with One-Time Universal Hashing

Accurate and tamper-resistant timestamps are essential for applications demanding verifiable chronological ordering, such as legal documentation and digital intellectual property protection. Classical timestamp protocols rely on computational assumptions for security, rendering them vulnerable to...
