Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Winter/wn backend module, software state validation or input boundaries are circumvented during processing.

"details" : "### Impact\nUsers with access to backend forms that include a [ColorPicker FormWidget](https://wintercms.com/docs/v1.2/docs/backend/forms#color-picker) can provide a value that would then be included without further processing in the compilation of custom stylesheets via LESS. This had the potential to lead to a Local File Inclusion vulnerability.\n\nBy default, only the Brand Settings (backend.manage_branding) and Mail Brand Settings (system.manage_mail_templates) forms both include the colorpicker formwidget and pass the provided value to be compiled in LESS, however it is also common for themes to include it on their Theme Customization (cms.manage_theme_options) form and it is technically possible for the values on that form to also be used in LESS compilation: https://wintercms.com/docs/v1.2/docs/themes/development#asset-compiler-variables.\n\n### Patches\nThis issue has been patched in v1.2.4.\n\n### Workarounds\nApply https://github.com/wintercms/winter/commit/5bc9257fe2bc47d8b786a1b1bf96bafad23d8ddd manually if unable to upgrade to v1.2.4.",
