About this tag
The path-encoding tag on WindowsForum.com covers discussions around how crafted URIs, UNC paths, and encoded file references can exploit Windows security features. A key example is CVE-2025-54917, a Windows MapUrlToZone security feature bypass where path-encoding techniques trick the system into misclassifying a URL's zone, allowing remote content to bypass zone-based restrictions. This undermines browser and application sandboxing. The tag focuses on the intersection of path manipulation, encoding tricks, and Windows security mechanisms, particularly in enterprise IT and cybersecurity contexts.
