CVE-2026-53683: client-side open redirect in reset_password.html.
The page takes the url query parameter as a redirection target
without validating or allow-listing it, so an attacker can send a
user to an arbitrary site once the password reset completes. No
authentication is required, and the link appears to come from the
IdM domain, which makes it useful for phishing.
CVE-2026-86593: unauthenticated denial of service in the session
endpoints login_password, change_password and sync_token. They do
not limit the size of the request body, so an attacker can tie up
the WSGI worker pool. That pool serves the whole /ipa application,
so exhausting it also denies the Kerberos authenticated paths such
as the web interface and the admin RPC. This is the same root cause
already fixed for i18n_messages and migration.py, whose fix covered
only a single caller.
