CVE-2026-45695 Details.
Kopia Server 0.23.0 - Remote Code Execution
Atlas does not check this one. Needs an outside server.
To test for this one, the site would have to contact a server outside your network and report back. Atlas does not run checks that need that, so it does not run this one.
About CVE-2026-45695. What It Means.
Kopia before version 0.23.0 allows unauthenticated remote code execution when started in server mode with the --without-password flag. When the /api/v1/repo/exists endpoint is exposed, it enables instantiation of the SFTP storage backend with user-supplied sshArguments. Due to improper argument parsing, an attacker may inject arbitrary SSH options such as -oProxyCommand, resulting in execution of arbitrary commands as the server process.
