DRUPAL-CONTRIB-2026-281 (CVE-2026-118582)

Vulnerability from drupal – Published: 2026-10-28 17:27 – Updated: 2026-10-28 17:36 – Source website

Details

The CAPTCHA module places a configurable challenge on forms to block automated submissions. To skip the challenge on later steps of the same multi-step form, the module remembers that a CAPTCHA session has been solved.

The 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.

This is a follow-up to the earlier CAPTCHA replay fix (SA-CONTRIB-2026-015 / CVE-2026-3214), which closed one replay path but left this one open.
