Uncaught Exception
Overview Affected versions of this package are vulnerable to Uncaught Exception in the TLS module when a TLS server is configured with pskCallback or ALPNCallback. A remote attacker can crash or exhaust resources of a TLS server by sending input that causes the callback to throw an error...
Node.js: TLS PSK/ALPN Callback Exceptions Bypass Error Handlers, Causing DoS and FD Leak
A flaw was discovered in Node.js TLS error handling that allowed remote attackers to crash or exhaust resources of a TLS server when pskCallback or ALPNCallback were in use. Synchronous exceptions thrown during these callbacks bypassed standard TLS error handling paths, causing either immediate...
CVE-2025-65781: Improper Authentication
An issue was discovered in Wekan The Open Source kanban board system up to version 18.15, fixed in 18.16. Attachment upload API treats the Authorization bearer value as a userId and enters a non-terminating body-handling branch for any non-empty bearer token, enabling trivial application-layer Do...
BIT-NGINX-GATEWAY-2021-3618
ALPACA is an application layer protocol content confusion attack, exploiting TLS servers implementing different protocols but using compatible certificates, such as multi-domain or wildcard certificates. A MiTM attacker having access to victim's traffic at the TCP/IP layer can redirect traffic fr...
