The KDE Connect protocol 8 before 2025-11-28 does not correlate device IDs across two packets. This affects KDE Connect before 25.12 on desktop, KDE Connect before 0.5.4 on iOS, KDE Connect before 1.34.4 on Android, GSConnect before 68, and Valent before 1.0.0.alpha.49.
Weakness
This attack-focused weakness is caused by incorrectly implemented authentication schemes that are subject to spoofing attacks.
