Answer in brief
CVE-2026-67599 records a High severity (CVSS 7.2) vulnerability in ClearOS 7.9 OS Command Injection via Log Viewer filter parameter. The current sources do not mark it as known exploited. The current feed maps ClearFoundation/ClearOS (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.2. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

ClearOS 7.9 contains an OS command injection vulnerability in the Log Viewer component that allows authenticated attackers to execute arbitrary commands by submitting unsanitized input through the filter parameter, which is interpolated directly into a shell command in File.php. Attackers can inject command substitution payloads into the filter parameter to execute arbitrary commands as the webconfig user, and due to extensive NOPASSWD sudo privileges granted to that user by default, immediately escalate to root.
