CVE-2025-14946 is a medium-severity vulnerability rated 4.8/10 on the CVSS scale. A flaw was found in libnbd. A malicious actor could exploit this by convincing libnbd to open a specially crafted Uniform Resource Identifier (URI). EPSS estimates a 0.12% chance of exploitation in the next 30 days.

Description

A flaw was found in libnbd. A malicious actor could exploit this by convincing libnbd to open a specially crafted Uniform Resource Identifier (URI). This vulnerability arises because non-standard hostnames starting with '-o' are incorrectly interpreted as arguments to the Secure Shell (SSH) process, rather than as hostnames. This could lead to arbitrary code execution with the privileges of the user running libnbd.
