DescriptionGitHub Advisory

Vikunja is a todo-app to organize your life. Prior to 1.1.0, TaskGlanceTooltip.vue temporarily creates a div and sets the innerHtml to the description. Since there is no escaping on either the server or client side, a malicious user can share a project, create a malicious task, and cause an XSS on hover. This vulnerability is fixed in 1.1.0.

AnalysisAI

Cross-site scripting (XSS) in Vikunja prior to version 1.1.0 allows authenticated attackers to execute arbitrary JavaScript in other users' browsers by injecting malicious code into task descriptions that are rendered without sanitization in hover tooltips. An attacker can exploit this by sharing a project and creating a specially crafted task that triggers the vulnerability when other users hover over it. …
