"The version of Adobe Creative Cloud installed on the remote macOS host is prior to 6.8.0.821. It is, therefore, affected
by a vulnerability as referenced in the APSB25-95 advisory.

  - Creative Cloud Desktop versions 6.7.0.278 and earlier are affected by a Time-of-check Time-of-use (TOCTOU)
    Race Condition vulnerability that could lead to arbitrary file system write. A low-privileged attacker
    could exploit the timing between the check and use of a resource, potentially allowing unauthorized
    modifications to files. Exploitation of this issue does not require user interaction. (CVE-2025-54271)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
