CVE-2023-48135: 
NixOS vulnerability analysis and mitigation

An issue in mimasakafarm mini-app on Line v13.6.1 allows attackers to send crafted malicious notifications through the exposure of the channel access token. The vulnerability was discovered and disclosed on January 26, 2024, affecting the Line application's mini-app functionality ([GitHub Report](https://github.com/syz913/CVE-reports/blob/main/mimasakafarm.md), NVD).

The vulnerability is classified as an exposure of sensitive information (CWE-200) with a CVSS v3.1 base score of 5.4 (Medium). The issue occurs when the mini-app 'mimasakafarm' exposes the channel access token in the response of the request to www.l-members.me/miniapp/memberscard. This token is used for securing communication channels within Line and should be kept confidential (GitHub Report).

The vulnerability affects all users of the mimasakafarm mini-app. When exploited, attackers can utilize the exposed channel access token to broadcast malicious messages through the Line platform, including potentially fraudulent information and malicious website links ([GitHub Report](https://github.com/syz913/CVE-reports/blob/main/mimasakafarm.md)).

As of the time of disclosure, there is no specific mitigation information available from the vendor. The fundamental fix would require securing the channel access token and ensuring it's not exposed in client-side responses (GitHub Report).
