What is CVE-2025-8597?

A configuration flaw in MacVim on macOS allows local attackers with unprivileged access to attach debuggers, altering or reading process memory and injecting code within the application context. This vulnerability exploits the 'com.apple.security.get-task-allow' entitlement, bypassing the typical user permission prompts required for greater access. Attackers can utilize this flaw through malicious applications, gaining access to resources previously permitted by the user, while other permissions necessitate user interaction. This issue was rectified in build r181.2.
