CVE-2024-42218: 
NixOS vulnerability analysis and mitigation

1Password 8 before version 8.10.38 for macOS contains a security vulnerability (CVE-2024-42218) that allows local attackers to exfiltrate vault items by bypassing macOS-specific security mechanisms. The vulnerability was discovered by the Robinhood Red Team during a security assessment and was responsibly disclosed to AgileBits, with no reports of exploitation in the wild (NVD, Help Net Security).

The vulnerability leverages outdated versions of 1Password that contain vulnerabilities in third-party dependencies and lack security hardening measures present in modern versions. The issue has been assigned a CVSS v3.1 base score of 6.3 (Medium) with the vector string CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N, indicating that it requires local access with standard or low user privileges and is complex to exploit, though no user interaction is needed (1Password Support).

A successful exploitation could allow attackers to exfiltrate vault items and obtain derived values used for signing in to 1Password, specifically the account unlock key (AUK) and 'SRP-x' values. The vulnerability affects the confidentiality and integrity of the stored data, though it does not impact system availability (1Password Support).

The vulnerability has been patched in 1Password 8 version 8.10.38, released in August 2024. Users running affected versions of 1Password 8 for Mac are strongly advised to update to the latest version. It's worth noting that 1Password 7 for Mac is not affected by this vulnerability (1Password Support).

AgileBits has acknowledged that this vulnerability demonstrates the importance of not only patching security vulnerabilities in the latest version but also ensuring that past versions cannot automatically access secrets in newer versions. The company has committed to remaining vigilant about protecting their apps and users against this style of attack (1Password Support).
