CVE-2019-13053

CVE-2019-13053 is a keystroke injection vulnerability affecting Logitech Unifying receivers and their firmware, stemming from an incomplete fix for a prior vulnerability. An attacker within radio frequency range can inject keystrokes by sniffing cryptographic data and pressing a specific "magic" key combination, bypassing encryption. This medium-severity vulnerability (CVSS 6.5) requires adjacent network access and low attack complexity, with a high impact on integrity but no impact on confidentiality or availability. While there is no evidence of active exploitation, public exploit code, or KEV listing, the vulnerability has garnered some community discussion and media coverage.
