CVE-2026-90767
Froxlor before 2.3.12 SSH Key Injection via authorized_keys
Description
Froxlor before 2.3.12 fails to properly validate multi-line SSH public keys in the SshKeys::add() endpoint, allowing customers to inject arbitrary lines into authorized_keys files. Attackers can inject malicious SSH key entries with option directives to gain persistent unauthorized access that survives key deletion and SSH access revocation.
