CVE-2024-7457 — The ws.stash.app.mac.daemon.helper tool contains a vulnerability caused by an incorrect use of macOS’s authorization model

High CVSS 7.8

The ws.stash.app.mac.daemon.helper tool contains a vulnerability caused by an incorrect use of macOS’s authorization model. Instead of validating the client's authorization reference, the helper invokes AuthorizationCopyRights() using its own privileged context (root), effectively authorizing itself rather than the client. As a result, it grants the system.preferences.admin right internally, regardless of the requesting client's privileges. This flawed logic allows unprivileged clients to invoke privileged operations via XPC, including unauthorized changes to system-wide network preferences such as SOCKS, HTTP, and HTTPS proxy settings. The absence of proper code-signing checks further enables arbitrary processes to exploit this flaw, leading to man-in-the-middle (MITM) attacks through traffic redirection.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
