CVE-2025-29903

Arbitrary library execution via insecure macOS flags

Published Mar 12, 2025 · Updated Mar 12, 2025

Untrusted search paths in JetBrains Runtime before 21.0.6b872.80 allow local users to execute arbitrary dynamic libraries on macOS. The vendor identifies insecure macOS flags as the cause but does not disclose which runtime binary or flag-handling operation admits an untrusted library path. Low privileges and local access are required; successful exploitation runs attacker-controlled library code in the runtime's security context.
