Dualsafe Password Manager Digital Vault Extension
Monthly
DualSafe Password Manager & Digital Vault Extension (versions up to and including 1.4.35 for Chrome) exposes stored credentials and TOTP codes through an unauthenticated postMessage-based bridge, enabling cross-origin secret exfiltration by any webpage the victim visits. The extension's bridge component processes incoming postMessage calls without validating the sender's origin, meaning an attacker-controlled page can query the vault directly without any extension-level authentication. A publicly available proof-of-concept hosted on GitHub demonstrates the technique; the vulnerability has not been added to the CISA KEV catalog as of this analysis.
