Detailed vulnerability description
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences. The software fails to prevent globally-installed binaries to be overwritten by other
package installs. For example, if a package was installed globally and
created a serve binary, any subsequent installs of packages that also create a serve binary would overwrite the first binary.
Remediation
Update to version 1.1.6.
