CVE-2026-24126Network attack vector

Authenticated data exposure via SSH option injection

Published Feb 18, 2026 · Updated Feb 18, 2026

Argument injection in Weblate before 5.16.0 allows remote authenticated users to expose data through crafted SSH host input. The management console's SSHAddForm passed an unvalidated hostname to the SSH key-scanning subprocess, allowing a leading hyphen to be interpreted as an option. High-privilege console access is required; the vendor reports confidentiality impact but does not identify the exposed data.
