Official Description

Plesk contains an XPath injection vulnerability in the APS Application Catalog search functionality, where user-supplied input is interpolated into XPath queries without proper sanitization. This allows an authenticated, low-privileged user to execute arbitrary operating system commands on the server, resulting in local privilege escalation.

Risk Analysis

This critical vulnerability in Plesk's APS Application Catalog search functionality allows an authenticated, low-privileged user to execute arbitrary operating system commands. The flaw stems from improper sanitization of user input in XPath queries, leading to XPath injection. With a CVSS score of 9.9, this vulnerability can result in local privilege escalation and full system compromise.

No public exploit is currently known for this vulnerability. However, its remote exploitability and low attack complexity mean it could be exploited by an attacker with low privileges.

Recommended Action

Administrators should apply any available patches or upgrades for Plesk that address XPath injection vulnerabilities. Ensure that all user-supplied input is properly sanitized before being used in XPath queries or other backend operations.

Technical Analysis

CVE-2026-44962 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.9.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
