CVE-2026-56850

CVE-2026-56850 affects Node.js 22.x, 24.x, and 26.x. The issue is in the HTTPS Agent’s connection reuse, where PFX object-array key collisions can cause mutual TLS (mTLS) client identities to be reused across requests with different client certificates. This could enable cross-certificate identit...

📄 PAN-OS GlobalProtect Authentication Bypass

This Python proof of concept exploit targets an authentication bypass vulnerability in PAN-OS GlobalProtect by attempting to forge authentication cookies using publicly exposed TLS certificate material. Versions prior to 12.1.4-h6 are affected...

CVE-2026-8932

libcurl would reuse a previously created connection even when some mTLS config related option had been changed that should have prohibited reuse. libcurl keeps previously used connections in a connection pool for subsequent transfers to reuse if one of them matches the setup. However, some TLS...

Improper Verification of Cryptographic Signature

Overview Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature in the integratedTime verification process. An attacker can bypass certificate validity checks by providing a bundle with a manipulated integrated time, potentially allowing the reuse of ...

TLS Certificate Reuse Analyzer

Python-based TLS auditing utility that connects to multiple remote hosts, retrieves their presented TLS certificates, fingerprints each certificate, and compares those fingerprints to identify certificate reuse across systems. It also records basic TLS metadata such as protocol version, cipher...

CVE-2026-32324
