An unauthenticated attacker could leverage this vulnerability to call functions against the installer to perform high privileged actions. Exploitation of this issue does not require user interaction.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
