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 in Adobe Creative Cloud Desktop that can lead to arbitrary file system writes. It affects Creative Cloud Desktop versions 6.7.0.278 and earlier (all versions prior to 6.8.0.821) on macOS. The vulnerability was published on October 15, 2025, with initial NVD analysis completed on October 17, 2025. It carries a CVSS v3.1 base score of 5.6 (Medium), assigned by Adobe (Adobe Advisory, NVD).

The vulnerability is classified as CWE-367 (Time-of-check Time-of-use Race Condition). An attacker exploits the window of time between when the application checks a resource (e.g., a file path or permission) and when it actually uses that resource, allowing a malicious substitution — such as a symbolic link swap — to redirect file operations to unintended locations. This is consistent with CAPEC-27 (Leveraging Race Conditions via Symbolic Links) and CAPEC-29 (Leveraging TOCTOU Race Conditions). The attack vector is local, requires low privileges, has high attack complexity, and does not require user interaction, with the scope of impact extending beyond the vulnerable component (NVD, Adobe Advisory).

Successful exploitation allows a low-privileged local attacker to perform unauthorized writes to arbitrary locations on the file system, resulting in a high integrity impact with no confidentiality or availability impact. On macOS, this could enable an attacker to overwrite sensitive system or application files, potentially facilitating privilege escalation or persistence. The changed scope indicates that the impact can extend beyond the Creative Cloud Desktop process itself to other components or system resources (NVD).

Adobe has released a patched version of Creative Cloud Desktop (6.8.0.821) that resolves this vulnerability. Users running version 6.7.0.278 or earlier on macOS should update to version 6.8.0.821 or later immediately via the Creative Cloud Desktop application or Adobe's official download channels. No configuration-based workarounds have been published; upgrading is the recommended remediation (Adobe Advisory, NVD).

The vulnerability was included in Adobe's October 2025 patch batch, which was noted by security aggregators such as BeyondMachines and CIS, the latter issuing an advisory on multiple Adobe vulnerabilities that could allow arbitrary code execution. No notable individual researcher commentary or significant social media discussion has been identified for this specific CVE (CIS Advisory).
