vulnerability as referenced in the MMSA-2025-00504 advisory:

  - Mattermost Desktop App versions <6.0.0 fail to enable the Hardened Runtime on the Mattermost Desktop App 
    when packaged for Mac App Store which allows an attacker to inherit TCC permissions via copying the 
    binary to a tmp folder. (CVE-2025-13326)
