Claude AI Just Cracked a Post-Quantum Test Scheme and Found a Faster 7-Round AES Attack

Anthropic says Claude Mythos Preview helped derive an end-to-end key-recovery attack against HAWK-256 and a 200- to 800-fold speedup for an attack on seven-round AES-128. The HAWK attack exploits a previously unused symmetry in the lattice behind the signature scheme. Anthropic's released...

openssl: OpenSSL TLS 1.3 server may choose unexpected key agreement group

A key group selection preference flaw has been discovered in OpenSSL. An OpenSSL TLS 1.3 server may fail to negotiate the expected preferred key exchange group when its key exchange group configuration includes the default by using the "DEFAULT" keyword. A less preferred key exchange may be used...

JLSEC-2026-757 Use-after-free in PQC hybrid key-share handling

Use-after-free in PQC hybrid key-share handling. This is an incomplete-fix follow-up to CVE-2026-5460 released in 5.9.1: a malicious TLS 1.3 server sending a truncated PQC hybrid KeyShare can still trigger the error cleanup path to operate on freed memory...

A heap use-after-free exists in wolfSSL's TLS 1.3 post-quantum cryptography PQC hybrid KeyShare processing. In the error handling path of TLSXKeyShareProcessPqcHybridClient in src/tls.c, the inner function TLSXKeyShareProcessPqcClientex frees a KyberKey object upon encountering an error. The call...

Protection mechanism failure in wolfCrypt post-quantum implementations ML-KEM and ML-DSA in wolfSSL on ARM Cortex-M microcontrollers allows a physical attacker to compromise key material and/or cryptographic outcomes via induced transient faults that corrupt or redirect seed/pointer values during...

Deserialization of Untrusted Data

Overview Affected versions of this package are vulnerable to Deserialization of Untrusted Data through the deserializeMetadata paths in AwsSecretsManagerKeyLifecycleManager, HashicorpVaultKeyLifecycleManager, and the legacy metadata migration path in FileBasedKeyLifecycleManager. An attacker can...

CVE-2026-43867

The CVE concerns Apache Camel’s PQC component where AwsSecretsManagerKeyLifecycleManager.deserializeMetadata() Base64-decodes and deserializes persisted KeyMetadata via a raw java.io.ObjectInputStream.readObject() without an ObjectInputFilter or class allow-list. A user who can write to the confi...

CVE-2026-43867

Deserialization of Untrusted Data vulnerability in Apache Camel PQC Component. The camel-pqc component persists post-quantum key metadata KeyMetadata through pluggable KeyLifecycleManager implementations. AwsSecretsManagerKeyLifecycleManager.deserializeMetadata reads that metadata back from the...

PT-2026-55886

☕ Apache Camel critical alert: CVE-2026-43867 hits the camel-pqc component. Post-quantum key metadata deserialized via ObjectInputStream with zero ObjectInputFilter — unauthenticated RCE risk at CVSS 9.8. Check your Camel builds now. AppSec Apache https://t.co/iaMBNrOfI0 https://t.co/mkIJ19Sd5Y...

Accelerating the quantum-safe timeline

The quantum-safe timeline has changed For years, planning for post-quantum cryptography PQC was framed as a future problem: important, inevitable, but distant. That perspective is evolving as technology advances and organizations prepare for the scale and complexity of the transition ahead. At...

PostgresSQL JDBC -- Silent channel-binding authentication downgrade via unsupported certificate algorithms

PostgreSQL project reports: channelBinding=require connections can be silently downgraded from SCRAM-SHA-256-PLUS with channel binding to plain SCRAM-SHA-256 without it, losing the man-in-the-middle protection the setting is meant to guarantee. An attacker who can intercept the TLS connection...

CVE-2026-7531 Use-after-free in PQC hybrid key-share handling

Use-after-free in PQC hybrid key-share handling. This is an incomplete-fix follow-up to CVE-2026-5460 released in 5.9.1: a malicious TLS 1.3 server sending a truncated PQC hybrid KeyShare can still trigger the error cleanup path to operate on freed memory...

CVE-2026-7531

CVE-2026-7531 describes a use-after-free in the handling of PQC hybrid key-shares for TLS 1.3. The issue occurs when a malicious server sends a truncated PQC hybrid KeyShare, which can trigger the error cleanup path to operate on freed memory. Documents consistently label this as an incomplete fi...

Trump Order Sets 2030 Deadline for Federal Post-Quantum Crypto Migration

President Trump signed an executive order on June 22 setting hard deadlines for federal agencies to move high-value assets and high-impact systems to post-quantum cryptography. Key establishment must move by December 31, 2030; digital signatures by December 31, 2031. EO 14409 leaves national...

Post-Quantum Cryptography Is Coming, but Your DNS Might Not Be Ready

The Clock Is Already Ticking: Why Post-Quantum Cryptography Can’t Wait

There is a question I have been hearing more and more from CISOs, compliance officers, and security architects over the past year. It does not start with "we had a breach" or "we failed an audit." It starts with something that sounds almost philosophical: " Are we quantum-safe?" A year ago, that...
