CVE-2025-15224

When doing SSH-based transfers using either SCP or SFTP, and asked to do public key authentication, curl would wrongly still ask and authenticate using a locally running SSH agent...

CVE-2025-13034

When using CURLOPTPINNEDPUBLICKEY option with libcurl or --pinnedpubkey with the curl tool,curl should check the public key of the server certificate to verify the peer. This check was skipped in a certain condition that would then make curl allow the connection without performing the proper chec...

Post-Quantum Cryptography Key Expansion Method and Anonymous Certificate Scheme Based on NTRU

NTRU is one of the important lattice-based post-quantum cryptography methods, offering resistance against quantum computing attacks. However, a drawback of NTRU lies in its relatively low efficiency in generating key pairs. Therefore, this study proposes an NTRU-based key expansion method that...

PT-2026-2253

Name of the Vulnerable Software and Affected Versions Cosign versions prior to 2.6.2 and 3.0.4 Description Cosign is a tool providing code signing and transparency for containers and binaries. Prior to versions 2.6.2 and 3.0.4, a crafted Cosign bundle could successfully verify an artifact even if...

CVE-2025-53627

Meshtastic is an open source mesh networking solution. The Meshtastic firmware starting from version 2.5 introduces asymmetric encryption PKI for direct messages, but when the pkiencrypted flag is missing, the firmware silently falls back to legacy AES-256-CTR channel encryption. This was an...

Correctness of Extended RSA Public Key Cryptosystem

This paper proposes an alternative approach to formally establishing the correctness of the RSA public key cryptosystem. The methodology presented herein deviates slightly from conventional proofs found in existing literature. Specifically, this study explores the conditions under which the choic...

Meshtastic 安全漏洞

Meshtastic is a decentralized wireless off-grid mesh network LoRa protocol open-sourced by Meshtastic. A security vulnerability exists in Meshtastic versions 2.5 up to and including 2.7.15, which stems from a degradation attack path in the absence of PKI cryptographic flags, and could lead to an...

curl: CVE-2025-15224: libssh key passphrase bypass without agent set

A vulnerability was discovered in the libcurl libssh backend where the CURLOPTSSHAUTHTYPES option did not properly implement the CURLSSHAUTHAGENT flag. As a result, if the CURLSSHAUTHPUBLICKEY option was set, the implementation would act as if CURLSSHAUTHAGENT was always defined, allowing...

When RSA Fails: Exploiting Prime Selection Vulnerabilities in Public Key Cryptography

This paper explores vulnerabilities in RSA cryptosystems that arise from improper prime number selection during key generation. We examine two primary attack vectors: Fermat's factorization method, which exploits RSA keys generated with primes that are too close together, and the Greatest Common...

A First Look at Common RPKI Publication Practices

The RPKI is crucial for securing the routing system of the Internet. With the RPKI, owners of Internet resources can make cryptographically backed claims, for example about the legitimate origin of their IP space. Thousands of networks use this information to detect malicious or accidental route...

CVE-2025-67897

A flaw was found in Sequoia. This vulnerability allows a remote attacker to crash an application via sending a victim an encrypted message with a crafted Public Key Encrypted Session Key PKESK or Symmetric Key Encrypted Session Key SKESK packet, which causes aeskeyunwrap to panic when processing ...

Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation via the PKI realm. An attacker can impersonate other users by presenting specially crafted client certificates signed by a trusted Certificate Authority. Note: This is only exploitable if the attacker...
