Secure and Efficient Quantum Signature Scheme Based on the Controlled Unitary Operations Encryption

Quantum digital signatures ensure unforgeable message authenticity and integrity using quantum principles, offering unconditional security against both classical and quantum attacks. They are crucial for secure communication in high-stakes environments, ensuring trust and long-term protection in...

CVE-2025-53548

Clerk helps developers build user management. Applications that use the verifyWebhook helper to verify incoming Clerk webhooks are susceptible to accepting improperly signed webhook events. The issue was resolved in @clerk/backend 2.4.0...

Improper Verification Of Cryptographic Signature

Clerk is vulnerable to improper verification of cryptographic signature. The vulnerability is due to the use of the verifyWebhook helper, which may accept improperly signed webhook events, allowing an attacker to forge webhook requests and potentially trigger unauthorized actions...

Hybrid LLM-Enhanced Intrusion Detection for Zero-Day Threats in IoT Networks

This paper presents a novel approach to intrusion detection by integrating traditional signature-based methods with the contextual understanding capabilities of the GPT-2 Large Language Model LLM. As cyber threats become increasingly sophisticated, particularly in distributed, heterogeneous, and...

Security Bulletin: IBM watsonx Orchestrate Cartridge affected by vulnerability in elliptic-6.5.4.tgz

Summary IBM watsonx Orchestrate Cartridge contains a vulnerable version of elliptic-6.5.4.tgz Vulnerability Details CVEID:CVE-2024-48948 DESCRIPTION: The Elliptic package 6.5.7 for Node.js, in its for ECDSA implementation, does not correctly verify valid signatures if the hash contains at least...

CVE-2025-42992

SAPCAR allows an attacker logged in with high privileges to create a malicious SAR archive in SAPCAR. This could enable the attacker to exploit critical files and directory permissions without breaking signature validation, resulting in potential privilege escalation. This has high impact on...

CVE-2025-49600

A flaw was found in mbedtls. The mbedtlslmsverify function may accept forged Leighton-Micali signatures when hash computation fails and internal error conditions are not properly checked. This flaw allows an attacker with physical access to create invalid signatures. This issue occurs because...

SUSE CVE-2025-49600

In MbedTLS 3.3.0 before 3.6.4, mbedtlslmsverify may accept invalid signatures if hash computation fails and internal errors go unchecked, enabling LMS Leighton-Micali Signature forgery in a fault scenario. Specifically, unchecked return values in mbedtlslmsverify allow an attacker who can induce ...

CVE-2025-53359

ethereum is a common ethereum structs for Rust. Prior to ethereum crate v0.18.0, signature malleability according to EIP-2 was only checked for "legacy" transactions, but not for EIP-2930, EIP-1559 and EIP-7702 transactions. This is a specification deviation. The signature malleability itself is...

Missing Cryptographic Step

Overview Affected versions of this package are vulnerable to Missing Cryptographic Step in the mbedtlslmsverify process when internal errors from the createmerkleleafvalue and createmerkleinternalvalue functions are not checked. An attacker can cause the acceptance of invalid signatures by induci...
