What is CVE-2026-67608?

The TVox versions 26.5.3 and earlier, as well as 24.9.21 and prior, contain a significant OS command injection flaw located in the action_audio.php file. This vulnerability allows authenticated attackers to execute arbitrary operating system commands by manipulating the unsanitized 'pid' parameter in an exec() function. When the 'action' parameter is set to 'checkProcess', this flaw can be exploited to run malicious commands with the privileges of the apache user, potentially leading to unauthorized access or system compromise.

Affected Version(s)

TVox 26.0.0 <= 26.5.3

TVox 26.0.0 <= 26.5.3

TVox 24.0.0 <= 24.9.21

Exploit Proof of Concept (PoC)
