The Entity List module, enabling entity list creation without Views, contains a remote code execution vulnerability exploitable via other contributed modules or custom code, with at least one known unauthenticated exploit path.
The Navigation module contains a cross-site scripting (XSS) vulnerability due to insufficient sanitization of certain attributes, exploitable only by users with specific permissions such as 'administer menu' or the ability to enter HTML tags with certain data attributes.
The Drupal core Link module has insufficient sanitization of certain markup in internal and external URLs, leading to cross-site scripting (XSS) vulnerabilities.
Gin, an administration theme providing a modern and customizable backend UI, contains an XSS vulnerability due to insufficient sanitization of certain attributes, exploitable by users with specific HTML input or administer menu permissions.

"category": "description",
"text": "De kwetsbaarheden betreffen meerdere modules binnen Drupal. In de Field UI module en de Entity List module is een remote code execution kwetsbaarheid aanwezig die kan worden misbruikt via contributed modules of custom code, waarbij sommige aanvalspaden geen authenticatie vereisen. De Navigation module, Link module en het Gin administratie thema bevatten cross-site scripting (XSS) kwetsbaarheden veroorzaakt door onvoldoende sanitatie van bepaalde HTML- of URL-attributen. De XSS-kwetsbaarheden kunnen alleen worden misbruikt door gebruikers met specifieke permissies, zoals het invoeren van HTML met bepaalde data-attributen of de \u0027administer menu\u0027 permissie. De kwetsbaarheden zijn specifiek voor Drupal installaties die deze modules of thema\u0027s gebruiken en kunnen leiden tot ongeautoriseerde code-uitvoering of scriptinjectie.\n\nDe kwetsbaarheden zijn niet zondermeer te misbruiken, maar vereisen een plugin of externe module waarmee de kwetsbaarheid kan worden misbruikt. Het is daarom aan te raden om geen gebruik te maken van onbekende, en onvertrouwde, plugins en externe modules.",
