CVE-2026-49449: Exposure of Sensitive Information to an Unauthorized Actor

Joplin is an open source note-taking and to-do application that organises notes and lists into notebooks. From 1.4.0 until 3.7.2, packages/renderer/MdToHtml/rules/katex.ts enables KaTeX's trust option for note content, allowing a note author to place a \href URL into rendered output without passi...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Before versions 6.9.13-48 and 7.1.2-23, the distributed pixel cache was originally designed to work without a challenge-response authentication model. This has been changed in versions 6.9.13-48 and...

Deep-Fake CAPTCHA: Mitigating Next-Generation Social Engineering Attacks

This paper presents DF-CAPTCHA, an active defense against real-time deepfake impersonation in voice and video calls. Instead of passively searching for artifacts, DF-CAPTCHA prompts the caller to perform simple challenge-response tasks that are easy for humans but difficult for current real-time...

A Drop-In KEM Replacement for Client Signatures in Post-Quantum SSH

The transition to post-quantum cryptography is reshaping the Secure Shell SSH protocol for remote administration. Post-quantum key exchange has been deployed in OpenSSH and is being standardized, while SSH authentication largely remains a signature-replacement effort. This path preserves the...

A Study of Bluetooth Access Control Based on NFT Soft Pairing

This paper proposes a Non-Fungible Token NFT soft pairing framework for Bluetooth service access control. Unlike conventional Bluetooth systems where pairing implicitly grants persistent service access, the proposed approach decouples native Bluetooth pairing from authorization without modifying...
