CVE-2025-55076 describes a local privilege escalation vulnerability in the Plugin Alliance Installation Manager v1.4.0 for macOS, specifically within its InstallationHelper service. This flaw allows an unauthenticated local user to execute arbitrary commands with root privileges by exploiting unauthenticated XPC connections and the service's use of system() for input execution. Rated as MEDIUM severity with a CVSS score of 6.2, it requires local access but has low attack complexity, potentially leading to full system compromise. Currently, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
