Detailsinfo

A vulnerability was found in MacVim up to 181.1. It has been declared as problematic. This vulnerability affects an unknown functionality. The manipulation with an unknown input leads to a information expsure vulnerability. The CWE definition for the vulnerability is CWE-497. The product does not properly prevent sensitive system-level information from being accessed by unauthorized actors who do not have the same level of access to the underlying system as the product does. As an impact it is known to affect confidentiality. CVE summarizes:

MacVim's configuration on macOS, specifically the presence of entitlement "com.apple.security.get-task-allow", allows local attackers with unprivileged access (e.g. via a malicious application) to attach a debugger, read or modify the process memory, inject code in the application's context despite being signed with Hardened Runtime and bypass Transparency, Consent, and Control (TCC). Acquired resource access is limited to previously granted permissions by the user. Access to other resources beyond granted permissions requires user interaction with a system prompt asking for permission. According to Apple documentation, when a non-root user runs an app with the debugging tool entitlement, the system presents an authorization dialog asking for a system administrator's credentials. Since there is no prompt when the target process has "get-task-allow" entitlement, the presence of this entitlement was decided to be treated as a vulnerability because it removes one step needed to perform an attack. This issue was fixed in build r181.2

The weakness was released with Karol Mazurek. The advisory is available at cert.pl. This vulnerability was named CVE-2025-8597 since 08/05/2025. The exploitation appears to be easy.
