The call to i18n.T for notifications.task.overdue.overdue was missing
its first positional argument, so the translation key was being passed
as the language code. This surfaced as a "dead key" once the
translation check learned to look for unused entries. Fix the call so
the reminder line is properly localised.
Task titles, project titles, team names, doer/assignee names, and API
token titles were interpolated raw into Line(...) calls whose content is
rendered to HTML by goldmark and then sanitized with bluemonday UGCPolicy.
UGCPolicy intentionally allows safe <a href> and <img src> with
http/https URLs, so a title containing Markdown link or image syntax
would survive sanitization as a working phishing link or tracking pixel
in a legitimate Vikunja email.
Introduce notifications.EscapeMarkdown, which prefixes every CommonMark
§2.4 backslash-escapable ASCII punctuation character — including '<' so
autolinks like `<https://evil.com>` are neutralized before reaching
goldmark — with a backslash. Apply it to every user-controlled argument
of every Line(...) call in pkg/models that feeds into an i18n template,
and to the hand-built "* [title](url) (project)" Markdown link in the
overdue-tasks digest notification.
Also escape the migration error string in MigrationFailedNotification,
an additional sink not listed in the advisory (error messages can carry
user-controlled content from the external migration source).
Subject(...), Greeting(...), and CreateConversationalHeader(...) are
left unchanged: Subject is passed directly to the mail library and is
not markdown-rendered, Greeting is rendered via html/template's built-in
HTML escaping without markdown, and the conversational header is
sanitized as raw HTML by bluemonday in mail_render.go.
Fixes GHSA-45q4-x4r9-8fqj.
Add user_id column to webhooks table (nullable, for user-level webhooks
vs project-level). Extend webhook model, permissions, and listener to
support user-level webhooks that fire for user-directed events like
task reminders and overdue task notifications.
Add TasksOverdueEvent for dispatching overdue notifications via webhooks.
Update webhook permissions to handle both user-level and project-level
ownership. Add webhook test fixture and register webhooks table in test
fixture loader.
Convert task comment, mention, assignment, and reminder notifications
to use the conversational email format. Add Project field to notification
structs, include task identifiers in subjects and headers, add doer
avatars, notification settings links in footers, and From headers.
Email notifications now display user mentions with inline avatar images for improved visual recognition and easier identification. Mentions gracefully fall back to display names if avatars are unavailable.
If a task is overdue at the same time the notification is sent, it would contain a message like "overdue since" without a time. This now shows "overdue now" instead.
