Summary
AliasVault: Browser extension WebAuthn bridge accepts forged origin/RP ID
Details

AliasVault is a privacy-first password manager with built-in email aliasing. Prior to 0.29.4, the AliasVault browser extension passkey provider does not bind passkey requests to the actual webpage origin or verify that the requested relying-party identifier matches the current website. A malicious website can provide forged origin and relying-party values and, if a victim with a matching stored passkey approves the AliasVault passkey prompt, obtain a valid assertion for a different website. Exploitation requires the extension to be installed, unlocked, and configured as a passkey provider, requires a stored passkey for the impersonated site, and cannot occur silently because the victim must approve the prompt. The server, web application, and mobile applications are not affected. This issue is fixed in version 0.29.4.
