Drupal 9.2.18 Released
Drupal core's form API has a vulnerability where certain contributed or custom modules' forms may be vulnerable to improper input validation. This could allow an attacker to inject disallowed values or overwrite data. Affected forms are uncommon, but in certain cases an attacker could alter critical or sensitive data.
We do not know of affected forms within core itself, but contributed and custom project forms could be affected. Installing this update will fix those forms.
The solution is to install the latest version, if you are using Drupal 9.2, update to Drupal 9.2.18. All versions of Drupal 9 prior to 9.2.x are end-of-life and do not receive security coverage. Note that Drupal 8 has reached its end of life.
Drupal 7 is not affected.
