Adobe Photoshop Elements version 5.2 and earlier is affected by an insecure temporary file creation vulnerability. The vulnerability was disclosed on June 28, 2021, and affects both Windows and macOS operating systems. This security flaw allows an unauthenticated attacker to call functions against the installer to perform high-privileged actions without requiring user interaction (NVD, Adobe Advisory).

The vulnerability is classified under CWE-668 (Exposure of Resource to Wrong Sphere) and CWE-379 (Creation of Temporary File in Directory with Insecure Permissions). The CVSS v3.1 base score is 5.5 (Medium) with the vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N, indicating local access, low attack complexity, low privileges required, no user interaction needed, and high impact on integrity (NVD).

The vulnerability can lead to high-privileged actions being performed on the affected system. While there is no impact on confidentiality or availability, the integrity impact is rated as high due to the potential for privilege escalation through the installer functionality (NVD).
