CVE-2025-54271: 
Adobe Creative Cloud vulnerability analysis and mitigation

CVE-2025-54271 is a Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability affecting Adobe Creative Cloud Desktop Application versions 6.7.0.278 and earlier. The vulnerability was disclosed on October 15, 2025, and affects Adobe's Creative Cloud software suite (NVD, Adobe Security).

The vulnerability is classified as a Time-of-check Time-of-use (TOCTOU) Race Condition that could lead to arbitrary file system write. The vulnerability has been assigned a CVSS 3.1 Base Score of 5.6 (Medium) with the vector string CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:N/I:H/A:N, indicating local access required, high attack complexity, low privileges required, no user interaction needed, and high impact on integrity (NVD).

A successful exploitation of this vulnerability could allow a low-privileged attacker to perform arbitrary file system writes by exploiting the timing between the check and use of a resource. The vulnerability does not require user interaction for exploitation and could potentially lead to unauthorized modifications to files (CIS Security).

Adobe has released version 6.8.0.821 of the Creative Cloud Desktop Application to address this vulnerability. Users are advised to update to the latest version immediately after appropriate testing. Organizations should also apply the principle of least privilege to all systems and services, and run all software as a non-privileged user to diminish the effects of a successful attack (ASEC, CIS Security).
