A Denial Of Service vulnerability exists in the SVG Sanitizer module through 8.x-1.0-alpha1 for Drupal because access to external resources with an SVG use element is mishandled.

Locale module and dependent contributed modules in Drupal 6.x before 6.16 and 5.x before version 5.22 do not sanitize the display of language codes, native and English language names properly which could allow an attacker to perform a cross-site scripting (XSS) attack. This vulnerability is mitigated by the fact that an attacker must have a role with the 'administer languages' permission.

Drupal 6.x before 6.16 and 5.x before version 5.22 does not properly block users under certain circumstances. A user with an open session that was blocked could maintain their session on the Drupal site despite being blocked.

Drupal 5.x and 6.x before 6.16 uses a user-supplied value in output during site installation which could allow an attacker to craft a URL and perform a cross-site scripting attack.

Drupal versions 5.x and 6.x has open redirection

In PrestaShop 1.7.5.2, the shop_country parameter in the install/index.php installation script/component is affected by Reflected XSS. Exploitation by a malicious actor requires the user to follow the initial stages of the setup (accepting terms and conditions) before executing the malicious link.

In Symfony before 2.7.51, 2.8.x before 2.8.50, 3.x before 3.4.26, 4.x before 4.1.12, and 4.2.x before 4.2.7, validation messages are not escaped, which can lead to XSS when user input is included. This is related to symfony/framework-bundle.

In Symfony before 2.7.51, 2.8.x before 2.8.50, 3.x before 3.4.26, 4.x before 4.1.12, and 4.2.x before 4.2.7, a vulnerability would allow an attacker to authenticate as a privileged user on sites with user registration and remember me login functionality enabled. This is related to symfony/security.

In Symfony before 2.7.51, 2.8.x before 2.8.50, 3.x before 3.4.26, 4.x before 4.1.12, and 4.2.x before 4.2.7, when service ids allow user input, this could allow for SQL Injection and remote code execution. This is related to symfony/dependency-injection.

The PharStreamWrapper (aka phar-stream-wrapper) package 2.x before 2.1.1 and 3.x before 3.1.1 for TYPO3 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.
