CVE-2026-65711 is a high-severity vulnerability rated 8.6/10 on the CVSS scale. sysPass through version 3.2.11 contains an OS command injection vulnerability that allows authenticated administrators to execute arbitrary commands as the web server process user by setting a malicious backup path and triggering a backup. The FileBackupService builds a tar shell command via string concatenation, inserting the admin-configurable siteBackupPath setting without escapeshellarg() or equivalent sanitization before passing it to exec(), causing injected commands to persist and execute on every subsequent backup trigger.. EPSS estimates a 2.41% chance of exploitation in the next 30 days.
