Of the 76 open code scanning alerts, 39 point at code that can change. svc-ai-mcp-adapter: - A path argument that is empty or made only of dots is refused. Percent-encoding keeps a separator inside its segment, but "." and ".." need none, so an upstream that resolves dot segments could answer from a path the contract does not name. - parse_duration splits on the units. The pattern it used before rescanned a long run of digits from every start position. Tests and the README generators: - Every Jinja environment built with autoescape=False and a "noqa: S701" uses select_autoescape now, as six test modules and utils/templating/jinja.py already did. It escapes templates named *.html, *.htm and *.xml, which none of these call sites loads. - Dead code goes: a doubled "rel" block in the email lint, an unread _SKIP_DIRS, and a module that _resolve returned to no caller. - Two "except ...: pass" blocks become contextlib.suppress and assertRaises. - Nine test modules import unittest.mock one way instead of two, and one lookup test imports its module once.

"""Whether Roundcube forces https on its generated URLs, per canonical scheme.
|
|
|
|
Roundcube derives the OAuth ``redirect_uri`` from the request scheme, and the
|
|
reverse proxy speaks plain HTTP to the container. Forcing https is therefore
|
|
right on a clearnet vhost and wrong on an onion one, which is served over HTTP
|
|
because Tor carries the encryption. Getting it wrong is not cosmetic: Keycloak
|
|
compares the ``redirect_uri`` against the client's registered list verbatim and
|
|
answers "Invalid parameter: redirect_uri" on a scheme mismatch, so the webmail
|
|
login dies before the form is ever drawn.
|
|
|
|
Both sides are built from ``canonical_url``, so the assertion here is that the
|
|
template follows that one source rather than a hard-coded scheme.
