Summary#

The security PR bundles multiple issues that share one root cause: treating uploaded paths and content as inherently safe. A strong default is to constrain file access to approved roots and force risky content types into download-safe behavior instead of inline rendering.

Problem#

Uploads and file preview endpoints can enable stored XSS or path traversal when content types are rendered inline or filesystem paths are insufficiently bounded.

Solution#

Normalize and validate paths against an allowed directory, prevent traversal outside the intended root, and serve SVG/XML or other user-provided content as downloads or otherwise non-renderable responses.

Failure Modes#

  • Path normalization happens after file access decisions, leaving traversal gaps
  • Browsers content-sniff uploaded files into executable contexts
  • Fixing one endpoint but not parallel preview/load routes leaves the same vulnerability class elsewhere
