CVE-2026-6478 PostgreSQL discloses MD5-hashed passwords via covert timing channel

Covert timing channel in comparison of MD5-hashed password in PostgreSQL authentication allows an attacker to recover user credentials sufficient to authenticate. This does not affect scram-sha-256 passwords, the default in all supported releases. However, current databases may have MD5-hashed...

CVE-2026-6478

CVE-2026-6478 enables a covert timing channel during MD5 password comparison in PostgreSQL authentication, allowing credential recovery sufficient to authenticate. The issue does not affect scram-sha-256 passwords. It can affect databases with MD5-hashed passwords originating from upgrades from P...

CVE-2026-42256 net-imap: Denial of service via high iteration count for `SCRAM-*` authentication

Net::IMAP implements Internet Message Access Protocol IMAP client functionality in Ruby. From versions 0.4.0 to before 0.4.24, 0.5.0 to before 0.5.14, and 0.6.0 to before 0.6.4, when authenticating a connection with SCRAM-SHA1 or SCRAM-SHA256, a hostile server can perform a computational...

SUSE CVE-2026-42198

pgjdbc is an open source postgresql JDBC Driver. From version 42.2.0 to before version 42.7.11, pgjdbc is vulnerable to a client-side denial of service during SCRAM-SHA-256 authentication. A malicious server can instruct the driver to perform SCRAM authentication with a very large iteration count...

CVE-2026-44405

A flaw was found in Paramiko, a Python implementation of the SSHv2 protocol. The rsakey.py module allows the use of the SHA-1 cryptographic hash algorithm, which is known to have security weaknesses. An attacker on the same local network, with significant effort, could potentially exploit this to...

Use of a Broken or Risky Cryptographic Algorithm

Overview paramiko is a library for making SSH2 connections client or server. Affected versions of this package are vulnerable to Use of a Broken or Risky Cryptographic Algorithm in the RSA key handling by allowing the use of the SHA-1 algorithm. An attacker can compromise the integrity of...
