rioterm is vulnerable to Command Injection
78
CVE Score
High
Command Injection
TL;DR
On Windows, the terminal hint feature opens URLs and file paths detected in terminal output by passing the matched text to a launcher configured as cmd with /c start. Because the standard library only quotes arguments that contain whitespace or a quote character, cmd metacharacters such as & in terminal-displayed text reach the command interpreter as syntax rather than data, so text after them runs as a separate command. Externally influenced output written to the terminal can therefore execute arbitrary commands once a user opens the hint. The fix removes the shell launcher default and hands the target to the platform default handler as a single string.
How do I fix this?
Upgrade the rioterm library to the patch version.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you run the terminal on Windows with the default hint configuration.
