An issue exists in the Drupal core Link module, which provides a field type for internal and external URLs. The module fails to sufficiently sanitize certain markup in specific circumstances, leading to Cross-Site Scripting (XSS), a condition where malicious scripts are injected into trusted websites.

Insufficient validation of certain inputs allows an attacker to perform Server-Side Request Forgery (SSRF), a technique where the server is coerced into making unauthorized requests to internal or external resources.

Drupal core contains a cross-site scripting (XSS) issue due to improper neutralization of input during web page generation. The XSS filter does not sufficiently sanitize certain attributes from the integrated HTMX JavaScript library, allowing an attacker to execute malicious scripts if they can insert HTML with specific attributes.

A Cross-Site Request Forgery (CSRF) issue affects the Drupal OAuth2 Client, allowing unauthorized actions to be performed on behalf of the user. This issue may be exploited by an attacker to perform actions without the user's knowledge or consent.
