What is CVE-2026-34883?
CVE-2026-34883 is a medium-severity path traversal vulnerability in n/a, published on 19 May 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
An issue was discovered in the Portrait Dell Color Management application before 3.7.0 for Dell monitors. On Windows, a symbolic link vulnerability allows a local low-privileged user to escalate privileges to Administrator. During installation, the software writes the file CCFLFamily_07Feb11.edr to C:\ProgramData\Portrait Displays\CW\data\i1D3\ while running with elevated privileges. Because the installer does not properly validate symbolic links or reparse points at the destination path, an attacker can create a malicious link that redirects the write operation to an arbitrary system location, enabling arbitrary file creation or overwrite with elevated privileges.
Weakness: CWE-59
