- http/raw.go: strip Windows backslash separators from archive entry names
on any host. filepath.ToSlash is a no-op for "\" on Linux, so a stored
backslash filename was emitted verbatim and could escape the extraction
directory on Windows extractors (zip-slip). (GHSA-gxjx-7m74-hcq8)
- http/auth.go: cap the login and signup request bodies with
http.MaxBytesReader (1 MiB). The JSON decoder previously read an
arbitrarily large password into memory before bcrypt truncated it,
enabling unauthenticated memory-exhaustion DoS. (GHSA-w5fm-68j4-fpc4)
- files/file.go, http/resource.go: add files.WithinScope and refuse to
follow a symlink whose on-disk target escapes the user's scoped root,
on both the read path (stat) and the write path (writeFile). Prevents a
scoped user from reading/overwriting/sharing files outside their scope
via a pre-existing escaping symlink. (GHSA-239w-m3h6-ch8v)
