Loading vulnerability…
Drupal core does not properly sanitize certain filenames for uploaded files. As a result, an attacker can upload a file whose name is interpreted as having a different extension than intended, causing the file to be served with an incorrect MIME type and, under certain hosting configurations, potentially treated as PHP and executed. Affected versions: Drupal Core 9.0.x prior to 9.0.8, 8.9.x prior to 8.9.9, 8.8.x prior to 8.8.11, and 7.x prior to 7.74.
