CVE-2025-1398: macOS TCC Bypass via Code Injection

Noroxi assessment

Priority: Monitor (action score 13/100)

The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
Fixed version: mattermost-desktop (npm) 5.11.0.

Low priority for now. Upgrade to mattermost-desktop (npm) 5.11.0 or later.
