Local privilege escalation via world-writable application bundle
Published Mar 26, 2025 · Updated Oct 3, 2025
Local privilege escalation in Fast CAD Reader 4.1.5 and earlier allows local users to execute code through macOS Dylib hijacking. The macOS application bundle is installed with rwxrwxrwx permissions, allowing any local account or process to replace bundle content with a malicious dynamic library. A guest or standard account must already have local access; launching the altered application executes attacker-controlled code with privileges unavailable to that account.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
