SUSE CVE-2025-68113
ALTCHA is privacy-first software for captcha and bot protection. A cryptographic semantic binding flaw in ALTCHA libraries allows challenge payload splicing, which may enable replay attacks. The HMAC signature does not unambiguously bind challenge parameters to the nonce, allowing an attacker to...
Quantum-Resistant Cryptographic Models for Next-Gen Cybersecurity
Another threat is the development of large quantum computers, which have a high likelihood of breaking the high popular security protocols because it can use both Shor and Grover algorithms. In order to fix this looming threat, quantum-resistant cryptographic systems, otherwise known as...
NGCaptcha: A CAPTCHA Bridging the past and the Future
CAPTCHAs are widely employed for distinguishing humans from automated bots online. However, current vision based CAPTCHAs face escalating security risks: traditional attacks continue to bypass many deployed CAPTCHA schemes, and recent breakthroughs in AI, particularly large scale vision models,...
GHSA-6GVQ-JCMP-8959 ALTCHA Proof-of-Work Vulnerable to Challenge Splicing and Replay
Impact A cryptographic semantic binding flaw in ALTCHA libraries allows challenge payload splicing, which may enable replay attacks. The HMAC signature does not unambiguously bind challenge parameters to the nonce, allowing an attacker to reinterpret a valid proof-of-work submission with a modifi...

A command injection vulnerability was discovered in TeamViewer DEX former 1E DEX, specifically within the 1E-Explorer-TachyonCore-FindFileBySizeAndHash instruction prior V21.1. Improper input validation, allowing authenticated attackers with Actioner privileges to inject arbitrary commands...
CVE-2013-10031
Plack-Middleware-Session (Perl) versions before 0.17 are vulnerable to HMAC comparison timing attacks. Affected component: Plack::Middleware::Session; root cause is a timing-attack vulnerability in HMAC comparison. Impact is described as a potential exposure via timing differences, with no explic...
CVE-2025-66511
Nextcloud Calendar is a calendar app for Nextcloud. Prior to 6.0.3, the Calendar app generates participant tokens for meeting proposals using a hash function, allowing an attacker to compute valid participant tokens, which allowed them to request details and submit dates in meeting proposals. The...
