CVE-2025-62686 Details
Description
A local privilege escalation vulnerability exists in the Plugin Alliance InstallationHelper service included with Plugin Alliance Installation Manager v1.4.0 on macOS. Due to the absence of a hardened runtime and a __RESTRICT segment, a local user may exploit the DYLD_INSERT_LIBRARIES environment variable to inject a dynamic library, potentially resulting in code execution with elevated privileges.
A local privilege escalation vulnerability exists in the Plugin Alliance InstallationHelper service included with Installation Manager versions through 1.4.0 on macOS. The vulnerability arises because the binary lacks a hardened runtime and a __RESTRICT segment, allowing local users to exploit the DYLD_INSERT_LIBRARIES environment variable to inject dynamic libraries. This injection could lead to code execution with elevated privileges, as the InstallationHelper runs as root.
To address this vulnerability, the Plugin Alliance InstallationHelper should be updated to include a hardened runtime, add a __RESTRICT segment to the Mach-O binary, and sanitize the environment at startup to clear DYLD_INSERT_LIBRARIES and other DYLD-related variables before the helper executes.
