CVE-2025-53811: TCC Bypass via misconfigured Node fuses in Mosh-Pro

• Severity: medium (CVSS 4.8 v4.0)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.1% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2025-08-26 · updated 2026-08-31
• Weakness: CWE-276

Description

The configuration of Mosh-Pro on macOS, specifically the "RunAsNode" fuse enabled, allows a local attacker with unprivileged access to execute arbitrary code that inherits Mosh-Pro TCC (Transparency, Consent, and Control) permissions.  Acquired resource access is limited to previously granted permissions by the user. Accessing other resources beyond previously granted TCC permissions will prompt the user for approval in the name of Mosh-Pro, potentially disguising attacker's malicious intent.  This issue was fixed in 1.3.7 version of Mosh-Pro.

Affected products

• Mosh-Pro: through 1.3.6
