1Password 8 before 8.10.36 for macOS allows local attackers to exfiltrate vault items because XPC inter-process communication validation is insufficient.

1Password 8 before 8.10.38 for macOS allows local attackers to exfiltrate vault items by bypassing macOS-specific security mechanisms.

An issue was discovered in AgileBits 1Password, involving the method various 1Password apps and integrations used to create connections to the 1Password service. In specific circumstances, this issue allowed a malicious server to convince a 1Password app or integration it is communicating with the 1Password service.

1Password for Mac 7.2.4 through 7.9.x before 7.9.3 is vulnerable to a process validation bypass. Malicious software running on the same computer can exfiltrate secrets from 1Password provided that 1Password is running and is unlocked. Affected secrets include vault items and derived values used for signing in to 1Password.

The Safari app extension bundled with 1Password for Mac 7.7.0 through 7.8.x before 7.8.7 is vulnerable to authorization bypass. By targeting a vulnerable component of this extension, a malicious web page could read a subset of 1Password vault items that would normally be fillable by the user on that web page. These items are usernames and passwords for vault items associated with its domain, usernames and passwords without a domain association, credit cards, and contact items. (1Password must be unlocked for these items to be accessible, but no further user interaction is required.)

A DLL injection vulnerability in 1password.dll of 1Password 7.3.712 allows attackers to execute arbitrary code.

AgileBits 1Password through 1.0.9.340 allows security feature bypass

An issue was discovered in 1Password 7.2.3.BETA before 7.2.3.BETA-3 on macOS. A mistake in error logging resulted in instances where sensitive data passed from Safari to 1Password could be logged locally on the user's machine. This data could include usernames and passwords that a user manually entered into Safari.

The 1Password application 6.8 for Android is affected by a Denial Of Service vulnerability. By starting the activity com.agilebits.onepassword.filling.openyolo.OpenYoloDeleteActivity or com.agilebits.onepassword.filling.openyolo.OpenYoloRetrieveActivity from an external application (since they are exported), it is possible to crash the 1Password instance.

Cross-site scripting (XSS) vulnerability in the Troubleshooting Reporting System feature in AgileBits 1Password 3.9.9 might allow remote attackers to inject arbitrary web script or HTML via a crafted User-Agent HTTP header that is not properly handled in a View Troubleshooting Report action.
