CVE-2024-42218

Vault-item exfiltration via missing biometric enforcement flag

Published Aug 6, 2024 · Updated Aug 8, 2024

Information disclosure in 1Password 8 before 8.10.38 for macOS allows local users to exfiltrate vault items from the app. The Mac client omits a biometric-enforcement flag, allowing an out-of-date app build to bypass macOS platform security protections. Exploitation requires control of the local device, such as through malware, and exposes stored secrets without reported service interruption.
