Astra Linux – Vulnerability in libssh

A flaw was discovered in libssh. A remote attacker, by controlling client configuration files or knownhosts files, could create specific hostnames that, when processed by the matchpattern function, could lead to inefficient regular expression backtracking. This could cause timeouts and resource...

CVE-2026-58065

The Apache Airflow Git provider runs its git-over-SSH operations with StrictHostKeyChecking=no by default, disabling SSH host-key verification. An attacker who can intercept the network path between an Airflow worker and the Git server can impersonate the server man-in-the-middle, capturing the S...

SUSE CVE-2026-12064

When a user invokes curl using a schemeless URL combined with --proto-default sftp or scp, a disconnect occurs between the tool layer and libcurl. The tool layer incorrectly infers the URL scheme, which erroneously bypasses the initialization of critical SSH security options like...

CVE-2026-9547

A flaw was found in curl. When a libcurl-based application uses SCP:// or SFTP:// for transfers and employs the CURLOPTSSHKEYFUNCTION callback, it may silently accept an untrusted server. This occurs if the server's host key type differs from the one stored in the knownhosts file. The callback...

Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation in the CURLOPTSSHKEYFUNCTION process. An attacker can intercept or manipulate data by presenting a server host key type that does not match the recorded key type in the knownhosts file, which is improperl...

CVE-2026-9547

When a libcurl-based application performs transfers via SCP:// or SFTP:// and utilizes the CURLOPTSSHKEYFUNCTION callback, it may silently accept an untrusted server. This vulnerability occurs when a server presents a host key type that does not match the specific key type already recorded for th...
