What is CVE-2026-65711?

The sysPass application, specifically version 3.2.11, is susceptible to an OS command injection flaw. This vulnerability allows authenticated administrators to exploit the backup functionality by maliciously altering the backup path. When the FileBackupService concatenates this input to construct a shell command, it fails to properly sanitize it using escapeshellarg() or an equivalent method. As a consequence, arbitrary commands can be executed under the privileges of the web server process user, posing significant security risks as these injected commands can persist and trigger on future backup operations.

Affected Version(s)

sysPass 0 <= 3.2.11

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
