Drupal core Cross-site Scripting (XSS) vulnerability in ckeditor
Cross-site Scripting (XSS) vulnerability in ckeditor of Drupal Core allows attacker to inject XSS. This issue affects: Drupal Core 8.8.x versions prior to 8.8.10.; 8.9.x versions prior to 8.9.6; 9.0.x versions prior to 9.0.6.

Improper access control
In some situations, the Image module does not correctly check access to image files not stored in the standard public files directory when generating derivative images using the image styles system. Access to a non-public file is checked only if it is stored in the "private" file system. However, some contributed modules provide additional file systems, or schemes, which may lead to this vulnerability. This vulnerability is mitigated by the fact that it only applies when the site sets (Drupal 9) $config['image.settings']['allow_insecure_derivatives'] or (Drupal 7) $conf['image_allow_insecure_derivatives'] to TRUE. The recommended and default setting is FALSE, and Drupal core does not provide a way to change that in the admin UI. Some sites may require configuration changes following this security release. Review the release notes for your Drupal version if you have issues accessing files or image styles after updating.

Cross-site Scripting
In Symfony, validation messages are not escaped, which can lead to XSS when user input is included.

Moderately critical - Third-party libraries - SA-CORE-2019-007
The `PharStreamWrapper` (aka `phar-stream-wrapper`) package does not prevent directory traversal, which allows attackers to bypass a deserialization protection mechanism, as demonstrated by a `phar:///path/bad.phar/../good.phar` URL.

Improper Input Validation
guzzlehttp/psr7 is a PSR-7 HTTP message library used in drupal. Versions prior to 1.8.4 and 2.1.1 is vulnerable to improper header parsing. An attacker could sneak in a new line character and pass untrusted values.
