The curl team has announced a fix for a high-severity vulnerability impacting libcurl and curl, a command-line tool widely used by developers. To update curl on various operating systems, users can follow these steps: On macOS, use Homebrew to install the latest version of curl (8.3.0) and modify the system path to prioritize the new installation. On Windows, use Winget or Chocolatey to install the latest version of curl and update environment variables accordingly. On Linux, use package managers like apt, snap, dnf, or apk to install the latest version of curl. Users can also build curl from source for the absolute latest version, but this requires more technical expertise. It is recommended to wait for official updates from Microsoft or adopt a newer version once available to ensure the latest security patch.
