## Technical details

A vulnerability exists in Microsoft PC Manager due to improper link resolution before file access (CWE-59), commonly known as a 'link following' or symlink attack. The flaw occurs when the application interacts with files without properly validating if the file path is a symbolic link or junction point. A local attacker with low-level privileges can create a malicious link pointing to a sensitive system file. When the PC Manager service or application performs operations on that link, it may inadvertently modify or access the target file with higher privileges, allowing the attacker to achieve full system compromise. The vulnerability is tracked as CVE-2026-50511 and requires local access to the target machine.
