CVE-2022-46256Network attack vector

Authenticated code execution via Pages path traversal

Published Dec 14, 2022 · Updated Apr 22, 2025

Path traversal in GitHub Enterprise Server allows remote authenticated users to execute code by building a GitHub Pages site. GitHub has not disclosed the affected file-handling locus or the operation that permits a crafted Pages build path to escape its intended directory. Exploitation requires permission to create and build a Pages site, after which code runs on the instance with server-side impact.
