CVE-2026-44405
Description
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 achieve a limited compromise of data integrity.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
