CVE-2026-102822

A flaw was found in russh. This vulnerability allows a remote attacker to cause a Denial of Service DoS by terminating active connection tasks. When a connection is configured to permit sessions without a Message Authentication Code MAC, improper algorithm negotiation allows pairing with block...

Astra Linux – Vulnerability in OpenSSH

In OpenSSH versions 5.7 through 8.4, there is an observable discrepancy that can lead to an information leak during algorithm negotiations. This vulnerability allows man-in-the-middle attackers to target initial connection attempts, where no host key has been cached by the client. NOTE: Some...

ROS-20260907-73-0062

The vulnerability in Erlang relates to the choice of a less secure algorithm during negotiation processes. Exploiting this vulnerability allows a remote attacker to execute a “man-in-the-middle” type attack...

EUVD-2026-51816

better-auth versions before 1.6.11 contain insecure cryptographic defaults in the oidcProvider and mcp plugins that advertise the none algorithm and accept plain PKCE by default. Attackers can exploit algorithm negotiation to accept unsigned tokens or intercept authorization codes when PKCE plain...

CVE-2026-6092: Selection of Less-Secure Algorithm During Negotiation

When HAVEENCRYPTTHENMAC is configured, the implementation could fall back to MAC-then-Encrypt rather than enforcing Encrypt-then-MAC...
