The Drupal project uses the third-party library CKEditor, which has released a security improvement that is needed to protect some Drupal configurations.
This module enables you to authenticate Drupal users using an external SAML Identity Provider.
If the site is configured to allow visitors to register for user accounts but administrator approval is required, the module doesn't sufficiently enforce the administrative approval requirement, in the case where the requesting user has already authenticated through SAML.
The Profile module enables you to allow users to have configurable user profiles.
The module doesn't sufficiently check access when creating a user profile. Users with the "create profiles" permission could create profiles for any users.
The SpamSpan module obfuscates email addresses to help prevent spambots from collecting them.
This module contains a spamspan twig filter which doesn't sanitize the passed HTML string.
This vulnerability is mitigated by the fact that sites must have custom twig template files that use the SpamSpan filter on a field that an attacker could populate. By default the SpamSpan module does not use the vulnerable twig filter.
The Drupal project uses the third-party library Archive_Tar, which has released a security improvement that is needed to protect some Drupal configurations.
Multiple vulnerabilities are possible if Drupal is configured to allow .tar, .tar.gz, .bz2 or .tlz file uploads and processes them.
Drupal 8 core's file_save_upload() function does not strip the leading and trailing dot ('.') from filenames, like Drupal 7 did.
Users with the ability to upload files with any extension in conjunction with contributed modules may be able to use this to upload system files such as .htaccess in order to bypass protections afforded by Drupal's default .htaccess file.
After this fix, file_save_upload() now trims leading and trailing dots from filenames.
