PgBouncer Crash PoC This repository contains a local proof of concept for a PgBouncer crash caused by an integer overflow in vulnerable PgBouncer versions. The included Docker setup builds PgBouncer 1.25.1, starts a PostgreSQL backend, enables SCRAM-SHA-256 authentication, and runs poc.py against...

Astra Linux – Vulnerability in dovecot

The attacker can use a specially crafted Base64 exchange between Dovecot and the client to forge SCRAM TLS channel bindings. This requires that the attacker be able to position themselves between Dovecot and the client connection. If successful, the attacker can eavesdrop on communications betwee...

Linux Distros Unpatched Vulnerability : CVE-2026-106428

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - An out-of-bounds read in SCRAM authentication response parsing in the MongoDB C Driver can read one byte beyond a fixed-size buffer when processing a malformed...

CVE-2026-106428

A flaw was found in the MongoDB C Driver. An out-of-bounds read occurs when the driver parses malformed responses during Salted Challenge Response Authentication Mechanism SCRAM authentication. A malicious server or network intermediary can exploit this flaw by sending a crafted response before...
