To skip the challenge on later steps of the same multi-step form, the module remembers that a CAPTCHA session has been solved.\n\nThe module does not fully invalidate a solved CAPTCHA session. As a result, a protected form that was already submitted once can be submitted again without solving a new CAPTCHA. This weakens the protection the module provides against automated submissions such as spam registrations, comment spam, and login brute-forcing.\n\nThis is a follow-up to the earlier CAPTCHA replay fix ([SA-CONTRIB-2026-015](https://www.drupal.org/sa-contrib-2026-015) / CVE-2026-3214), which closed one replay path but left this one open.","status":"published","published":"2026-10-28T17:27:47Z","modified":"2026-10-28T18:15:02.68214931Z","updated_at":"2026-11-02T15:46:13.900249Z"}]}}
