CherryTree through 1.7.2 contains an OS command injection vulnerability in CtActions::link_clicked that allows attackers to execute commands by embedding shell metacharacters in web link URLs. When the non-default Custom Web Link Clicked Action option is enabled, attackers can supply crafted documents whose links pass $(...), backticks, or semicolons unquoted to std::system, running commands as the victim on click.
